The other possibility is not making planetary economy of a non-matching type apply if you build stuff on or around it that either is something different, or works into one of the economy aspects applied. But that could come with its own problems.the solution is simple, allow the architect to block economy types at the port they dont want, leave the body strength itself alone.
… still, not having tourism always active on a station I want focused on agriculture around a (terraformable) water world, would be nice. I’m sure it would also make some sense to not have the weird quad mix of ELW economy to a colony outpost when you’re focusing on tourism or agriculture (as an example).
