'the idea of a free market itself is a utopian idea'
I think that's because many people assume a free market is something one has(handed down from on high), rather that something one does(bearing risk and being free to mitigate it).
'along with the illusory protection of the commons thu privatizing in libertarian thought.'
Don't know what libertarian thought you've consulted, but protection of the commons is illusory, for sure. 'Commons' means exclusive ownership when applied to something everyone owns... which, of course, is an oxymoron. There is no such thing.
In libertarian thought, 'privatization' simply means removing ambiguous laws, so that laws can be more consistently enforced. The bedrock of Protectionism/Cronyism is ambiguous, convoluted, overly-verbose legalese. These are the laws which strangely can't be interpreted and hence need a wise, beneficent clique of overlords to interpret it for the rest of us hapless, forlorn and otherwise-lost souls.
interesting, thanks
