the ideological justification behind privatizing everything is to make every man a king. the thing about that is, it means that any time you leave your kingdom you have to deal with several fickle idiot kings whose rules can change from moment to moment and who can ignore everyone and do whatever he wants without appeal. with public ownership there is one king, and he may suck but there are limits on what he can do and if we all don’t like what he does we can replace him or change the limits.
