All I know is I'm glad to be ideologically close(r) to libertarian than any other party right now.
As for the arguments about libertarianism and big business, I would argue that libertarianism, at least the hardcore types would have a lot of currently impossible offsets (such as no cap for liabilities in the case of disaster. If libertarians ran the US during the BP oil spill, there'd be no BP left to exist after the lawsuits), which would make big businesses rather difficult to exist. As others have said, a lot of the reason big businesses exist is due to their ability to manipulate laws and regulations that can and do stifle smaller competitors. If such regulations didn't exist, and companies could start up, operate, and compete quicker and easier with the big corporations, it would be much, much harder to monopolize power. Example: See the huge mortgage bailout of 2008.
Back from the dead, I'm afraid.
