So what's wrong with Socialism? What's wrong with letting the government own everything and coordinate the production, price and nature of goods and services?

One of the problems is what is says is the 200 million minds which are employed at their various tasks and have the various detailed knowledge of their jobs could be replaced with a smaller, smarter group of people and then things would be simpler, and more efficient.

Well, to start with, a smaller version of that is called monpolies. But you don't like monpolies. You don't like the choiceless, take it or leave it world that hands you. You don't like the total lack of customer service.

What Socialism says is that if we all cooperated, we'd be better off than if we all competed.

That presumes we all want the same things and can agree on what to do and how to do it. But the history of the world tells a different story, doesn't it?

At their heart, Socialism and Communism both believe they are the enlightened one, and deserve to run everything. The Soviets had their New Soviet Man. Communism has it's New Man. It's even a wikipedia page:

https://en.wikipedia.org/wiki/New_Man_(utopian_concept)

The only way to get everyone to agree to the extent they would have to in order for one entity to run everything would be to remake human beings themselves so they're all the same, so they all want the same thing and hold the same values. They need to "transcend" their concerns with their own selves, their selfishness, and be a kind of entity in a borg.

Some people in the 1800s and early 1900s when both these movements got going seriously believed this was both possible and desirable.

Fuck multicuturalism; you will be assimilated.

That's why all Socialsm is authoritarianism- no one is going to play the role you have in mind for them except at the point of a gun. Socialists never get voluntary coorperation for their schemes. They have to take over governments either through revolution or through deception and infilitration. Then reality hits. Then the gulags appear. Then the economy crashes, and the death squads start making the rounds, and you're eating dogs.

Lenin et.al. killed tens of millions. Mao killed 100 million. FDR was going to pack the Supreme Court. Harvard wants to criminalize homeschooling. It's all the same thing. By force, we will remake you. By force, we will shape people into our New Man. We are enlightened, you are ignorant and we will reform you and make you want what you should want.

Socialism doesn't work because the billions of individuals with their own hard-won accumulated life's knowledge , their own detailed lives making their own decisions using their own judgments, both in their jobs and in their personal lives can't have their self-willed actions be done "more efficiently" by a small, or large, coterie of like minded indivudals.

I the end, Socialism is for control freaks who simply fear the autonomous actions of other people, and have an aching need to control them. They're worried you might do something. You need to be controlled. By them.

In the end, Socialism is for narcissists and fantasists who believe for some reason, for example -INSERT UNIVERSAL GOOD THING HERE - that they deserve to decide everything. Equally absurdly they believe they and their buddys have the capacity and knowledge to do so more efficiently and with better outcomes than those other billions of minds.

In the end, Socialism never works because it's a stupid idea to begin with. A stupid idea promelgated by people who are, at their core, what we moderns call "assholes".
