"...  provide an example of "free market capitalism"? I don't think it exists ..."   For a discussion of the range of meanings for 'free market' in contemporary economic thought, see Wikipedia.  It doesn't necessarily mean 'total anarchy' or 'wholly unregulated', which is what (I assume) you wish to take the meaning to be.  

I *do* know of a couple 'free markets' out there that operate largely without any regulation, in the sense that you may mean.  They exist in some massive multiplayer online game - spaces, and are (as I understand it it) seriously studied by some economic researchers as examples of 'pure' laissez-faire capitalism.  Participation in such markets can be hilarious ... 

"... American-style regulated capitalism does create wealth ..." We agree here.  Some regulations help the creation of wealth - others may impede it.  And there can be conflicts of priorities that need be hashed out, as in any large, pluralistic society.
