Capitulating to the antisocial persons by just giving up just sends a message to others that this behavior is acceptable. It moves the Overton window. Someone who used to think turnstile hopping was the kind of thing only crooks and low-lifes do sees people doing it more and more, witnesses and hears about how there are no consequences, and can't help but reframe it as more like driving 70 in a 65mph zone -- a harmless thing that "everybody does" and is totally fine. The city has enough money, and after all, Mamdani said he'll make those rich guys pay more! That'll cover my share! Meanwhile transit deteriorates severely.
