Ok, but like, I clean my house, don't I? I hate that task, I would prefer to never have to do it, but living in filth is worse, so I clean.
I imagine it would be the same in communism at a community level. You have your local community park and it might not be fun to pick up garbage in it, but the community doesn't want their park to be covered in garbage, so they work together to give it the occasional cleaning!
We actually see this now, under capitalism even. Earth Day was last week, and I know of at least 3 different organized "clean up the park" events that happened in my local area. No one was paid for any of this work, and yet it happened, even in the capitalist hellscape that is the US.
