Are you aware of the history of the City of London Corporation? And its voting structure? If so, to try to equate it with any other government anywhere, seems rather disingenuous. If not, I suggest you have a look on wikipedia: http://en.wikipedia.org/wiki/City_of_London_Corporation
Yes, I worked in the City for years and considered living there as a resident too, when I was living in London. Just because it has an unusual structure doesn't alter the fact that it's a governmental body, and to claim otherwise because of its commercial roots is absurd.

Same deal with new York's subway - therre were private companies involved but they were set up within the frameworks of a public works project and were basically financial vehicles designed to limit financial liability and attract some matching capital from the private sector for an initial large public sector investment or monopoly grant.
I'm sympathetic to libertarianism but this notion that all this stuff would happen by itself if it weren't for evil government interference is just bollocks, it's just as stupid as communists claiming that all private capital is wicked.
