Anarcho-capitalism is about bringing force back to its proper use. We absolutely can and will force anarchism onto ourselves. That is, forcibly get everyone else to stop forcing us to do things.

And anyone who decides they want to join that paradigm, the government does not have complete ultimate power over them. The freedom to vote with your feet is still a realistic option for some. They have a choice to make.

And further, anarchists have the right to physically remove people and systems that tend toward statism, crime, or consolidation of power, and they will use it. And still again, cooperation in a free market is so superior to state regulated markets, that entire decentralized stateless regions will tend to have sustainable economic advantages against the statist world, and will drive motivated individuals to join the prosperity.

So I'm afraid your intuition is lacking in details about this stuff.
