Because this is not really true, see, the thing to remember is that:
-one, the tree is very much a cost effective asset, as most of of its biomass is stuck on hiding, to the point where even I am thinking of recycling it now that it did a demonstration of what it was thought for (proving that we can gain more from photosynthesis by placing it on the roof), we did actually get to see one that was more concentrated once and it gave about 1 biomass a day for about around 4 biomass if I remember correctly, and that was while not doing actions that would make it better
-two, the effect is not going to be linear, we were told that we can compound on words and that using the correct actions would make words more effective, here, we are placing a carrion eater with hydroponics and roots in a sewer, I very much expect it to give way more biomass than you seem to think
-and finally, three, the patrol is subject to more external factors, if Sabrina's mother isn't there for whatever reason? One less biomass, if the boxing ring is having problems? One less biomass. If we ends up being researched and need to use a new form to interact? Both biomass are lost.
Given all that, I want to learn more about how to be independent when it comes to making our own biomass, and hit that exponential curve as soon as possible to pass the bottleneck of being stuck to acting semi locally due to lack of biomass, remember, the QM herself implied that we're meant to be able to go global, and things like the patrol cannot sustain such a situation, so it is logical to think that the tools we had from the beginning can, hence me wanting to develop better generators.
We are at the beginning of the knowledge needed when it comes to making them, I want to experiment and learn more, it is very clear that the world's not going to wait for us, so we need to work on it instead of constantly putting it to tomorrow.
So I also think of the biomass generation in a sort of RTS way, but I think your assumptions are off here. I think of things in the terms of "resource nodes". If we want to generate biomass (efficiently at least) we need to tap some sort of external source. Each node has different requirements to tap.
Thing is, our patrol route is a
very efficient resource node. It only requires an asset with 2 biomass to tap, and always generates at least 2 biomass each turn. It also has other benefits like letting us keep appraised of events in our area, and keep up our attendance record at work. While in theory it could be disrupted by external factors, we haven't seen any evidence of such happening yet and if said external factors are going to happen then we likely would want to know.
So patrolling effectively fully pays for it's self every turn. While eventually other methods of biomass generation may beat it out on volume, I doubt they will ever beat it on efficiency. Not unless they use a similarly limited "resource node" like patrolling an area.
(I'll note that we haven't been getting biomass from Sabrina's mother most of the turns. It's one biomass from dumpster diving, one from the food which we share with Martin, and occasionally a third from Sabrina's mother. We have never gotten less then two so far.)
The best we ever got the Kudzu was 1 biomass every 2 days, and it had 5 keywords (though I guess only 4 of them came from biomass)
Name: Kudzu
Keywords: Photosynthetic, Growing, Bountiful, Productive, Refresh
It is March 27th, 1923. You will gain one biomass every two days (March 28th). Your current goals are to find someone who needs help, and help them, to investigate Herman's Theater of the Soul, and to close the Poster Portal (Time Limit: Ten Years). Your current Available Biomass is 1.
Given the sheer efficiency and other benefits keeping up patrolling just makes sense to me. I do want to to experiment with other sources of biomass generation, but considering everything else we are doing feel it can wait one turn. Approaching more then one girl at once is going to be vital to resolving the situation quickly.
Anyway, being reminded of Sabrina's mother perhaps we should update her on the situation? As far as she knows Sabrina just vanished. We might actually be able get some advice from her on what to say to the magical girls too! Plus she knows Sabrina better. And we are uh, kind of signing Sabrina up for a lot with the whole "Community service" plan.
[X] Plan: Spy Triplets
-[X] Recycle Underground Ghost
-[X] Recycle Architect
-[X] Remove Fast, Stalwart from Super-Spy
-[X] Add Exponential Growth, Empathetic, Stalwart, Disguise to our Core
-[X] Create an asset: Twin Spy
--[X] keywords: Humanoid, Disguise, Trustworthy
-[X] Add Magical Healer, Doctor to Super Spy
-[X] Spread yourself to *Your Tunnels* in the underground.
-[X] Send Super Spy to discuss with Laurie in the Back-Alley Market
--[X] You noticed she wasn't looking very well. You could try to heal her if she is okay with it?
--[X] Talk with her about her brother. You want to understand how things were between him and Sabrina, and why she blames Sabrina for what happened to him. You heard he had a journal?
--[X] Talk with her about Sabrina. Maybe you could talk to Sabrina about her brother? You doubt Sabrina would be happy to hear he died either. You know you aren't unbiased, but the Sabrina you know is not some unfeeling monster.
--[X] Talk with her about Martin, how he got addicted out of the government's fault, then left to rot. About how Sabrina was the one helping him. A poor solution yes, but the only one she had. How every day where she's not there to give them what they crave is one more day where they may decide to go to a dealer that is more willing to exploit them? How there are other young people like her that may see their sibling go through withdrawal and could even decide to blame her for it even if it's not true?
--[X] Yes, Sabrina should pay for her crimes, but the guards aren't interested in that, they just want to make examples, never thinking about the people they hurt on the way. Sabrina can pay for her crimes by helping those she hurts get better, by working for them, we are not asking Laurie to forgive her, we are asking her to allow the others that are suffering to also be helped.
--[X] Yes you could try to do it without her, but it's not just convenience. Time could be lives.
-[X] Send Twin Spy to discuss with Sylvia in the School Theater.
--[X] Explain a little of your situation to her and try to get to know her a bit in return. You are not a very normal person, but you do have normal parts to your life too. You work a normal job and get paid in normal money! You live in an normal (abandoned) building and talk to normal people every day!
-[X] Patrol Your Street with Alibi Spy
--[X] Stop by Sabrina's mother early and update her on the situation. She doesn't need to worry though you are working to resolve things! Perhaps she has some advice?
