Then you woke up.
Anarcho-capitalism isn't really a thing. Or at least, it isn't anarchism. It's essentially end-stage libertarianism. If you want to see what it looks like, Somalia is currently in such a situation. It ends up being less freedom and more feudalism with petty warlords all fighting for dominance. It's not unlike the Crips, Bloods, the Mafia, etc., just with everything instead of just with illegal vices.
This is all to say that this kind of anarchy would not be pleasant. Only teenagers, idiots, and assholes actually want it. Actual anarchism, by the way, is the end-stage of Communism. Totes different things.
Collective bargaining for wages is a bad thing? Warehouse workers earning more does not make you earn less.
Imagine if a bunch of tech bros said: "Hey, you don't need exercise. It's totally fine if your muscles atrophy. After all, we have technology to move you around and it can do so much more quickly than your muscles ever could!" We'd laugh them out of town.
Well, guess what? If you don't exercise your brain, it atrophies. If you outsource your thinking, you eventually become unable to think.
Nothing in progression can rest on its original plan. We may as well think of rocking a grown man in the cradle of an infant. -- Edmund Burke
