I think I misspoke earlier, when I said I was on Team Colonize Other Dimensions I don't think I meant actual legit colonization, I was very impaired around then so it's kind of a blur, but aware me wants to clarify I meant more... I'm on Team "Strip Mine Empty World's and Sick Jumba on The Dangerous Wildlife". Don't much care for the hassle of setting up a colony and making people live there and managing shit, we just set up a small outpost surrounded by a factory beyond the wildest dreams of any oil tycoon.
We can maximize our production without giving the slightest shit about pollution or long term habitation, there are plenty of fish in the sea, or worlds in the multiverse. Maybe keep one garden world for emergency evacuations of the populace. Never have to worry about resources again because we have entire other planets worth of the stuff at our backs.
This does require investing in portal tech, which I'm all for.
