Honest question, at what point does a workshop transition from ownable to not?

A small garage shop with a workbench and a tool wall is obvious enough, but can you own a separate workshop outside your home? Can it be far down the street, or out in a barn somewhere, or in the outskirts of town among large factories? Can you own a lathe? Can you own a CNC machine?

What tools are ownable and what tools are not? What's the scale-cutoff?

Bandsaws, drill presses, welders, large trucks, small trucks, cranes, sheet metal cutters and benders, pipe benders, etc.

Can you buy material? How much? Should it be limited by something else than your funds?

If you take on jobs that are too much for you to handle on your own, do you have to either make your means of small scale production communal, or give up the job?

Please draw some lines for me here.

Can you have your own garden for food?

I thought owning the means of production was the point, but requiring a consistent argument from a communist is like requiring a consistent argument from a communist.

How do new means of production come to be? Like, if a community really wanted a unicycle repair shop, how would that get started? How would it be decided that we use resources for that shop instead of, say, a pogo stick repair shop? Would that be up to a local government (or some other governing body)? Honest question.

Y'all should move to Cuba

And now infographics are memes... Shitposts has more memes than this community.

This isn't really a meme

No cars though. Fuck cars.

How's about a website that generates money, like Facebook or YouTube? Can you own that?

What about products that designed to create ongoing streams of revenue, like a patent on an invention or a piece of art you can collect royalties from every time it is displayed? The USSR famously took ownership of Tetris away from its creator.

Under communism, how does the stock market work? I'm not a big fan of it, but it's pretty hard to imagine getting rid of it now that the global economy is pretty much dependent on it.

Today, five countries exist that can be said to be communist: China, Russia, Vietnam, Laos, and Cuba. Of those five, none have achieved actual communism, and several have inarguably embraced capitalism to a great extent. All of them have essentially authoritarian governments. Which is unsurprising, since a dictatorship of the proletariat is central to the Marxist vision of how to create a communist society, and involves the creation of a single-party transitional government that forcibly suppresses all its critics and rivals.

I'm not big into capitalism and I think we should implement plenty of socialist reforms, but I will never understand why some people on the Left—or anyone for that matter—think communism is what we should be striving for.
