I mean, from a certain point of view she's right. "Crime" is a made-up word to describe things that go against the made-up rules society constructed in order to keep that society functioning.

Does that mean it doesn't exist, or that it shouldn't exist because you actually just figured this out? Fuck me, these people are so dumb.

Guess what? You were born in this society and are bound by its laws, whether you like it or not. If you want to live in an anarchist society go find one and live there. Too bad they don't exist, because every other person on the planet realised it's not viable.
