His argument is basically that all governments can become corrupted, so we should have no government. The first part of his argument is obviously true, but is far from sufficient justification for his conclusion. It completely ignores all the good things that come from government (social services, police, military defense). It also ignores that the lack of government can also become corrupted. In places like Somalis, where there was effectively no government, pseudo-governments form (like the various warlords, the Islamic Courts Union, and Al-Shabaab).
