You're begging the question "how would the presence of 'sheep' inhibit the success of voluntaryist systems?

The left-wing riots that we've just seen (including BLM, Antifa, etc) are a very expressive example. Imagine what would happen if their government checks went down to zero! And all the government-dependent "intellectuals" (college professors, politicians, lawyers, corrupt business cronies, etc) would lead them...

The only way to freedom is secession - to build voluntary new nations, focusing on quality of people rather their quantity. There should be myriads of competing start-up micronations (on land, seasteading, and eventually space-stations), each with its own membership criteria and contractual rules.

Being forced to live under socialism, with all brains and capital seceding from them, is exactly the punishment that the socialists deserve.
