Hmm… I’ll chew on this some more, but one thing that comes to mind, not sure if practical/doable: using a creative-creative portal inflicts a debuff that prevents using a creative-survival portal for a period of time (edit: BUT you could still use the portal if you go survival to creative, so you can get back to creative worlds… just not creative to survival). Say, a couple hours. Because you still have to have a survival home beacon, you aren’t stuck, still warp home then proceed from there; and because of this, not really too harsh a penalty, at least IMO (thinking of how I’d take it if I were playing). Then you could have purely creative free hubs, still have creative-survival portals in them, but they wouldn’t be too practical to use to bypass the survival portal economy unless you had a lot of time to kill.
