I am in favor of monopolies if they are market born. I am also in favor of people accumulating as much capital as they can. And I am against regulations of all kind.
But I can bare the libertarians that defend big corps when the State comes up with some bill or some new regulation that supposedly will hurt the big corps.
The reason is simple: 99.9999999999% of the time is all a show. The big corps are the ones that are pushing for the regulation. I mean, I don't see amazon, google, fb, etc lining up to sustain libertarianism or less regulations. In fact I often see them doing things to hurt people who fight the State. I see big corps giving money to statist politicians and they are often in the giving "advices" to lawmakers on how to build regulations.
And the reason is obvious: when you get big, you want rules. You want rules because they keep competition out. When you are big you can pay an army of lawyers, bribe officials when needed, and regulations will hardly affect your big corp. And even if it has some cost, it's nothing compared to the fact that you can keep out the competition that can't pay for the lawyers, the bribes and so on.
This is how all industries worked in human history: there is freedom, than big corps arrive and use the State to close the market. And while I understand if a socialist or a commie fall for it, I can't believe there are so many libertarians and ancaps that still fall for this trick.
I mean, I like the products that the corps put out on the market, but I can also see how they support big government, statist politicians, etc
So, I really wish liberty-minded people would stop sucking the cock of corporations.
