I tried to search if it's possible for a dev studio to release a game on Steam that works without it, by which I mean that if I uninstall Steam, the games keep working; I wasn't able to confirm, but it seems to be theoretically possible...

None of the games I have in my library work like that, but online some people suggest that some games work even without Steam, once installed.

Your point, however, still stands.
