The reason we have a corporatocracy now is due to the opposite of libertarianism: cronyism / crony-capitalism. When you have huge bureaucracy, you get a situation where corporations have to bribe (aka, lobby) for special rights, favors and bailouts. In a libertarian economy, a company would have to stand on it's ability to solve a marketplace demand.

Are you against voluntary society?

>a company would have to stand on it's ability to solve a marketplace demand.

This is the libertarian hand waving I complain about.

As long as you have a group with guns, companies will be paying that group to use their guns to enforce the rights of those companies. That's the most rational thing for a company to do. You can't out-innovate your competitors forever, you can't undercut their price forever and you can't provide better quality forever. Doing any of these things is very hard work, can be very expensive and you will lose eventually. It's a safer approach, once you win in a market to use those winnings to buy government-created barriers to entry against you're biggest enemy: new competition.

>Are you against voluntary society?

No, I assume it's inevitable given a large enough timescale. I have simply read enough to know that such a society is incompatible with capitalism.
