The argument is that:
People are flawed and imperfect and some are downright evil. So we have to put other people in charge to rule in order to keep things orderly and productive.The fundamental problem is that those rulers are as flawed, imperfect, or as downright evil as any other "normal" person. According to Hayek's treatise on socialism in The Road to Serfdom, certain kinds of political systems even encourage power-hungry, or fundamentally immoral people to become leaders. So you haven't solved the problem.
In fact you've made it worse. You've now given very corruptible people, very very big guns to point at people they find convenient.
On the flip side ... is the idea of Anarchism and Free-Market Anarchism really a solution? Is is a practical solution?
See it's the last question there that I struggle with. Market Anarchy is essentially flawless in its defense of personal liberty. But is it practical in its application to a small cluster of people? Maybe. But as the size of that "group" of Market Anarchists grows, you will get more and more negative externalities to deal with.
Can humans function in a society like that after having a love of authority and a willingness to obey ground into them? Perhaps eventually.
Could we build that future? Probably not any time soon. Too many people have made themselves dependent on the coercive and re-distributive actions of the state.
