I don't follow your thoughts here.

But. The state would likely regulate them away except maybe in climates that aren't very burdened by golf courses, if that's even a thing. Communist governments don't inherently take full control of all businesses. They simply eliminate private property, which is not to be confused with personal property.

A communist golf course might look like this. You roll right up to the course. You either pull out your own clubs or borrow some from the facility. Someone maybe informs you which courses are more or less busy, helps you understand how to play and what etiquette is expected for the pleasure and safety of yourself, other active and future golfers. And then someone maintains the courses when... whenever they're maintained now probably.

It's more that golf courses are generally wastes of land, and unless the proletariat deemed them necessary, golf courses would be either given back to the environment or repurposed for public housing or other such socially beneficial projects.
