Aaargh. It is tiresome to explain the obvious.
Capitalism is an economic - as opposed to a belief - system. [...] My preference is for freedom of contract, enforced by rational laws derived from the consent of the governed.
You are confusing the idea/theory/abstract model with the reality. Your mind is trapped.
Government make-work hacks and union thugs could not long survive in such an environment.
Pay attention to your own words. You used the word "could". You are talking about something what you IMAGINE that it can exist. It cannot.
If it's so bloody obvious, how come you can't cite a single example of "voluntary coercion"?
You are confusing the idea/theory/abstract model with the reality. Your mind is trapped.
I would say that it is your perceptions that are "trapped". The only barriers to economic freedom are imposed by a government unencumbered by rational law and empowered by those who wish to take by force what they have not created or earned. Capitalism isn't perfect because people aren't - nor are they perfectable. That is the uniform conceit of all utopian ideologies.

Obviously you've never lived in a socialist Hellhole like the People's Republic of Taxachusetts. Either that, or you work for the Registry of Motor Vehicles. That said, please substitute "would" for "could". Make-work hacks and do-nothing union jobs only thrive where economic value is subordinated to political clout.
