Realistically, Kenobi could be set exclusively on Tatooine, and I’d have no issues if that was what they did. The problem is that they chose to set so much of Mando and BoBF on Tatooine, also. That was the mistake. People are getting Tatooine fatigue now, right when we’re getting a show where it actually makes sense to have Tatooine.

And Tatooine is supposed to be a backwater, anyway. It’s meant to be the boondocks of the galaxy. It’s important on a meta level, but not in-universe.
