Authoritarianism inevitably results in state controlling the business. Or in different words, the state becomes the business. There is nothing free about that.
All power of any sort leads to abuse, power is basically the potential someone has to abuse and a disturbing chunk of humanity enjoy being terrible and will misuse any power they have.
But the problem with governmental/military/policing power is that people see abuse and their solution is often to try and create an even more powerful entity to fight it. Which should seem really stupid to anyone who has identified that the concentrated power was the problem in the first place. There are also less obvious problems with choosing conflict as a strategy; we should all be on fundamentally the same side.
That's how you concentrate even more power. So is it just an eternal rat race? Except nuclear weapons are the top so is the race over and no one can keep the power in check since no one can get more power than those with nukes?
Welcome to reality. If you want to tear down power you have to have power. If you tear down power some other group will go about concentrating power to you must keep power to monitor and stop them.
The problem with this sort of thing is that people can make good-sounding arguments on either side. I'd have interested to see more links to, like, correlational studies or something. Admittedly it's difficult to get anything out of these with high confidence, but I feel like you have to try.
