See Ayn Rand's "The Nature of Government" in VOS. Casey is pushing anarchism based on a false view of the nature of man.

You don't establish a government that isn't corrupt or doesn't become corrupt in an intellectual vacuum. The government you get and maintain depends on the dominant political philosophy of the culture, which depends on the dominant ethics and accepted ideas of how we can obtain knowledge and the nature of existence and man's relation to it.

Reform in government, let alone keeping it, is not possible without overthrowing the false dominating ideas of mysticism, subjectivism, altruism, collectivism and statism.

Maybe protection and maintain the good there before and to continue.

There is a quote that one of our founders supposedly stated that is something like "if men were angels, no government would be necessary".

Of course, as the article states, government is a relatively new concept who's intent is to protect the people from looters (including the government itself), which is how most civilizations were ruled until the US was established. How to keep it from becoming corrupt is the trillion dollar question that is yet to be answered. We failed that test in America.
