(self-described libertarian here:) you don't suppose that large organizations often become large because they benefit from government subsidy? Aside from obvious candidates like Boeing and Lockheed Martin, I personally think that the inflation/investment social model whereby individuals are pushed into stock market or mutual funds that trade stocks, is a stealth subsidy that selectively benefits large companies and incentivises corporate aggregation.
Obviously, my post is at best a sketch of a principle rather than a complete description of the economy and government as a whole :)
But the advantage of describing it in the terms that I did is that, yes, government subsidy can be a way that an entity generates more wealth than it is spending to obtain it. But it is only one way. If that particular way is special, it is only due to its especially feedback-isolating effects (being beholden to voluntary customers for money provides more direct feedback than being beholden to another over-large entity), rather than any special "government" badness.
