If AI replaced jobs one by one, these things should still have to exist, right?

I'm not sure I follow the logic here. I would still see all of this existing and even more due to demand. The idea with automation would be that everything that people want would still be there and even more. I would think we build more football stadiums, more hobby facilities, replacing business offices and other things we don't need with those.

I would also see e.g. video games being even greater than they are now, because people would be able to follow their passion and creativity and build games that won't require monetization and are unaffected by outside pressure. I have massive amount of video game ideas that I think would be super awesome, but not really easily monetizable. I would probably build a lot of them, especially with being able to do those so much faster with AI. If AI can do all the games by itself and doesn't require my or anyone's creativity, then super, I will just play them, because by definition they have to be better than anything so far, and if they are not, then by definition human creativity still matters there and they can build, either way seems good to me.

As for travel, I think there would be people out there doing this out of hobby, having pubs as a hobby thing, hosting people as a hobby, spreading their existing culture out of passion, not because they need to make money. I would actually prefer that type of travel over feeling like they only act friendly to me because I will be paying to them. In this case it would be visiting people who want you to visit them with no exchange of anything, both sides would be doing it out of curiosity or desire.
