All people are the same and every model you build has to take that into account. Neither government nor corporations are evil or good. Power is abused no matter where it is. Putting power in government is the same as power in corporations, because both are filled with normal people. We see this all the time, how many regulations have been broken and abused over the past 4 years in scandal after scandal, whether it is in housing, mining and drilling, banking.... Is more regulation going to solve this? More watchers to watch the watchers? Are we suddenly going to find honest people who are not corruptible to put in these positions? This isn't even getting into the corporations writing/lobbying for their laws, subsidies and loop holes. Just because you feel safer to think the guy in the Department of Interior is more honest and caring than a manager is some company, doesn't mean you need to spin libertarians as evil capitalist anarchists.
