The main argument between liberals and conservatives should be over how much regulation makes an economy well regulated. Let the left and the right fight over whether it should be total or totally absent. In other words, no principles should be involved in the field of politics. The only decision is how much theft and how much force shall be used and accepted to accomplish whatever goals the current power structure considers important. This is what Ayn Rand meant when she asserted that philosophers have forgotten that politics is a branch of philosophy.
Regulation is coercion, period.
All laws are ultimately enforced at the point of a gun, and I don't think that you are talking about prohibition of coercive crimes here. Force and freedom are opposites. In the real world, the people who end up in control are, more often then not, totally incapable of doing any creative or constructive work themselves. This is becoming more and more true as manipulators of organizations are taking over and engineers, scientists and manufacturers are becoming ever more rare in the halls of the executive wing. Power in government means ability to exert coercion, to force.
