Your post says far more about you than libertarians. Remember, every time you give the government a power, you are creating an avenue for corruption and by design putting someone who probably isn't qualified in charge of decisions they lack the experience to make reliably. There you go, a simple argument that increasing government power has a drawback that you never consider. And that's why you post says more about you than anything. Such an extreme position is impossible to defend and anytime you try either a) the person you are debating isn't very skilled at debating or b) you are just being stubborn and ignoring facts and arguments you don't like. I suspect its B.
And every time you remove legislation you open up entire new vistas of corporate depravity and as the last 40 years have comprehensively demonstrated, "market forces" are not a viable replacement for legislation. Increasing government power is a liability only and solely when folks make a habit of electing incompetents and the corrupt. Governance as a concept is fine, what you're actually arguing for is better politicians.
