It sounds like you're projecting your own insecurities about your inability to interact with whom you want to interact with. That's too bad.
The straw man argument about "giving up" roads, postal, internet etc is irrelevant to me. I'm not political. I believe in the feudalism that has existed since the dawn of agriculture. 80% of people are serfs, 20% are lords. I'll take advantage of the system that you serfs have created, be it political, corporate, even sexual markets.
I don't support the systems, and in a truly free market guys like me would be knocked down a notch.
But we aren't. I'm still making good enough money to vacation every week or two. I have great friends who either really like me, or like the things I have access to. I sleep with great women who also take care of my domestic needs. I don't work in a cubicle or in a "team environment" and I work with the customers I want to work with -- and ones who want to work with me.
And I work when I want to work. My employees have that same freedom: if they don't need the income, they don't have to come in and field new jobs. It's pretty basic, it's how humans seem designed to operate.
Or, you can be a serf in a 9-5 job paying off a mortgage for 42 years, college debt for 20+ years, and hope you'll die being able to leave your children something of value.
You can have your society, I don't want a part of it.
