Hm... I'm not sure I follow what one has to do with the other. Are you alluding to some sort of banana-republic-esque situation? Or just general anticompetitve/monopolistic behavior?
Just very generally. In a company there is generally no formalized structure to represent the opinion of the subjects in this case workers. Neither are there such structures in dictatorships.
For the sake of clarity, are you using quotes to reference some group who misappropriates the libertarian term? Or are you saying that the libertarian philosophy argues for an anti-democratic state?
I do not know what you mean when you say "libertarian philosophy", since things like libertarian socialism has very little overlap with "libertarianism" of the right. And there are the quotes again. I just think the word does not really seem appropriate in describing the philosophy when all I have heard from individuals defending it only reflect over the liberty to opress, never the liberty from escaping that opression.
