You're basically right, but then we intend on crafting an artificial afterlife in addition to that, don't we?
We intend to, but selling access to a facility you don't yet have the resources or ability to actually build it is generally considered a poor business practice at best.
I'm not saying he'd make an issue of it, but intangible costs are still costs. If it's not actually worship as
@Goldfish said then he shouldn't be a big issue, but I don't think that relying on people being too overawed by our power to say anything is a good idea.
For one thing, most people on Planetos don't actually know what a god is. Their image of one is head and shoulders above what the average deity is actually capable of. Any person perceived to act like they are a god will almost certainly be seen as an egomaniac, even if they actually have a modestly high divine rank. For another, most of the truly top tier stuff either isn't public or doesn't have enough context to mean anything to most people.
The average peasant would probably not see too much of a difference between a rumor about the dread sorcerer of the east signing a treaty with genies and negotiating with fey for control over the goblin market.
The intangible loss here is that even if we aren't confronted by it, a reputation for being "obviously mad with power" will influence how willingly and completely people work with you. If anything actually being powerful only makes it worse, because people will be afraid of the consequences of a dealing with a madman they can't run from or fight.
It probably won't be nearly that bad, but it could still be irritating and we wouldn't really know for sure until the reaction was wide spread enough to make it difficult to suppress.
If we can skip the whole thing by picking an approach that obscures what we're doing until it's been normalized why shouldn't we?
