Or, you know, government happens to be the best solution we have to certain types of coordination problems, some of which plague market economies.

But no, I'm sure literally everything government does that interacts with the market just creates corruption without sufficient benefit to outweigh any such harm, and it'd be better if we didn't do anything at all. Certainly it's easier to think about politics if we can permanently rule out an entire class of solutions this way, saving us from having to consider and weigh each per se. Bonus points if we can define "liberty" as "fewest things outlawed by government"—measuring that is way easier than trying to figure out the degrees of freedom of action available to ordinary people in practice.
