Authoritarian states are a very ineffective model. A leader can lead their small band of merry man to rob the highway alright. But it doesn't scale up to larger groups of people.
If you talk to the CEOs of large companies or miltary leaders, you find that they are unable to exert effective control of their organisations. The organisation will do whatever it wants to do. The leader can make their command but at every level through the organisation that command will be slightly subverted. The more layers, the less of that command will get through.
Since it's in the news, take for example Putin and Russia, Putin thought he had tank battalions that his lower downs had sold for parts decades ago. Based on the information in front of him, he should have taken Ukraine in several days regardless of resistance by the locals.
And whilst you might think it's impressive that he cut the budget in US congress to Ukraine, back-handed deals to send old Soviet equipment from 3rd party countries to Ukraine were made and now they are exhausted London is loaning Ukraine, Russia's money.
Putin's authoritarian Russia might be able to cut off the head of democracy but he's up against a five headed hydra. Democracy is a lot more scary than Authoritarism from a military perspective.
"You do not want your food supply being run according to democratic principles, you want it to work."
This is something that people don't really get, what's important is that the people delivering the food get the sack if they failed to do it. As long as that happens it's okay.
That's the reason why socialist and overly authoritarian countries have supply problems, they don't have an effective mechanism to replace failing organisations. Venezuela isn't able to extract Oil because the Oil dereks are run by the local dictator's family members.
