Theres a few differences between GTA and movies, but to focus on a big one, in GTA you have agency over your character. In a movie, its always a 3rd person perspective of somebody else breaking laws. In games, you are the one calling the shots.
I believe most people are rational enough to separate the fictional game world from reality, but by bringing reality closer to the game, I think it’s a valid concern that it will influence those who struggle with that to behave more like their avatar in the game.
I don’t think it’s a bad idea, it would be rather cool. but there is a bit of risk associated with it.
Edit: re-read the article and thought about it some more and I changed my mind. The risk I expressed is pretty negligible, and for the tourist impact it would probably be well worth it.
I thought that was exactly how copyright works. It is infeasible to keep track of every infringement, so a policy like that is unenforceable.
Also its not out of the question that those myriad of tetris clones each secured some sort of agreement with the tetris company.
