Continuing the discussion from US Forestry Service wages war on photography in national parks:
Money is irrelevent in this case.
Authoritarianism is about unquestioning obedience to authority figures, no matter how wrong, arbitrary or irrelevent to the well being of the organisation their commands are.
Samsung is an example of a big business authoritarian, one that is regarded as more powerful than the South Korean government. Just try keeping your job after you didn’t bow you head and avert your gaze when the chairman comes to visit. In Britain we don’t have to do that even when Liz Windsor is there.
Coca-cola is a small business authoritarian, as it outsources so much of its business to other companies (The US government agreed that it was a small business at one point, don’t know if they still do). All the promises about allowing unions are meaningless if they continue to outsource to anti-union companies.
As a side point, unions can also be authoritarian, and many big ones have been in the past. All organisations are at risk of becoming authoritarian, but we are talking about business right now.
All those are examples of how it is easier to have a monopoly with government. I see no evidence that the existence of a monopoly is impossible in a Libertarian-Capitalist region, especially the ones that are already here.
