I appreciate the honest capitalist-as-government take here because of how grisly a view it is in a pure form - essentially the claim is that government is neither for nor by the governed and it should only be used as a tool to further the interests dictated by the capital holders.
Personally I dont think this is anywhere near right or ideal - letting the movement of capital in free (as in speech not free as in beer) markets dictate what is produced by the economy at large has nothing to do with if a government should enact the will of its people or protect them. One is how and why governments exist (ie, democracy vs monarchy vs theocracy, etc) and one is how to plan an economy (capitalism vs various versions of a planned economy).
tl;dr - where government derives its power isn't the same as how an economy should decide what to make. Conflating the two is a way to hand-wave away a lot of harm done by unchecked greed.
