Confusing free market capitalism for crony-capitalist corruption is perhaps the most pervasive misconception about libertarianism. Libertarians view companies as groups of people who agree to cooperate in pursuit of goals that they cannot achieve separately. They welcome such cooperation, no matter on what scale it occurs, since they view human cooperation and the division of labour as fundamental to economic progress. The only proviso a libertarian would have is that companies operate on a level playing field in which customers voluntarily transact with them. They would oppose any group that benefits from theft, fraud, legal advantages that others do not enjoy, or a corrupt relationship with politicians.
