The DM. The DM is the final arbitrator on who tight or loose the rules will be. Players can play their game how they want. Why are you concerned about how other people play their game when it doesn't affect you?
At what point is up to that DM. That's it. DM runs the game how he wants. Players can decide if they like how that DM runs his game and whether they want to stay or not.
We had a player stick around for 2 sessions, because we were running a tighter to core game, and he wanted everything to be 'rule of cool' aka there are no rules. He left, and last I heard found another game. We play how we want, he plays how he wants... elsewhere.
