If regulation didn’t work, corpos wouldn’t fight so hard to dismantle them every step of the way. If they didn’t work, we wouldn’t see things get markedly worse every time they’re removed.

OK, they work, just both ways. Corps work to make them work more for them and less for everyone else. Since they have more power, they slowly succeed.

And ancap just sounds like all the worst bits of libertarianism taken to their illogical extreme and would produce one of the worst possible societies imaginable so why do any people here not hate ancap?

Ancap is one of the words for libertarianism.

and would produce one of the worst possible societies imaginable

I think a society valuing freedom and non-aggression above the rest in not that.
