I know all these utopian and ahistorical arguments of the so called ancaps very well, and I found, that most of these enthusiasts are employees, not self-employed. They even don't realise, that they are enslaved. They are too busy to think, while the real homines sapientes in the non-business-doing communities in the rain forests are dancing and living. This enthusiasm with production, markets and trade within a worldwide hypercollective has its origin in the christian labor (slave-) ethos, and the ancaps are unfortunate victims of this collectivist religion which is destroying the planet with exponentially increasing speed.
For a start Ancaps are NOT utopians.
Yes, I am enslaved. Here's how I define slavery. Being forced to give up the fruits of your labours. Having authorities tell you what you can and can't do, where you can and can't live and under what circumstances you will be permitted to earn money. All of this comes not from any justified authority, merely from historical tradition which when you examine it closely is revealed as complete BS. ie. the situation we are in right now that ancaps seek to extricate ourselves and everyone else from.
And what does it matter if an ancap is an employee or self-employed?
If the real people are dancing and living in the rain-forests why not go join them? Is it because it is a life of virtual poverty? There's a reason most people don't do that kind of thing anymore.
That reason is affluence and the ability and encouragement to exploit.

We called those the barbarous times, But if the forms have changed, the relations have remained the same, and the worker is forced, under the name of free contract, to accept feudal obligations." [Kropotkin, The Conquest of Bread, pp. 31-2]
Whoever labours becomes a proprietor --this is an inevitable deduction from the principles of political economy and jurisprudence. And when I say proprietor, I do not mean simply (as do our hypocritical economists) proprietor of his allowance, his salary, his wages, --I mean proprietor of the value his creates, and by which the master alone profits . . . The labourer retains, even after he has received his wages, a natural right in the thing he was produced." [What is Property?, pp. 123-4]
If ancaps arent utopian, anarchists arent either. An ideal world is a stateless world. capitalism and communism are impossible in a stateless world.
