People can get "addicted" to practically any type of entertainment in that they spend a massive chunk of their time on it to the point it stifles their development.
Is sports gambling worse than f2p games? Are f2p games worse than regular video games? Is someone addicted to video games worse than someone addicted to reading fantasy novels? What about smutty novels?
I'm not sure is disagree with you but I think it is hard to start drawing these lines without saying you are now the arbiter of good art and bad art and you can ban some forms of art if you don't like them and have decided they are bad.
Now are you just banning things you don't like because you point to the societal harms as a fig leaf defense that could be applied to the art you do like as well?
