Bingo. I had a tremendous respect for Molyneux before his slide into hypocrisy that began at that DCMA incident. He has produced some great material and he is a deep thinker.
I asked several folks who interacted with him regularly like Dana Martin what is going on with Molyneux and nobody has a good answer. Dana said he just stopped communicating with her and she added others were "cut off" at roughly the same time in much the same way.
I do have to agree with the person who replied to you:
And no, it's a pretty lousy assumption that property rights is what leads to centralization and monopolies.
It's not property rights that cause that. Monopolies wouldn't last long if government didn't provide subsidies and protections that encourage them.
I would like to draw your attention to below..specifically the "above all" part.
Of course we need to have private property right but its all about balance.
