You cannot opt out of capitalism to destroy it. At best you can save yourself from capitalism that way. If someone's plan to fight capitalism is to create a new community somewhere in the woods, they don't want to fight capitalism, they want to start a high control group nine times out of ten, the other one time out of ten they just want a few middle-class people to escape it.
Our mutual aid networks, our community organizations, our unions, must exist within the towns and cities of our nation, and must be things every worker has access to. That is what threatens capitalism. It's what scares them. They aren't scared by a commune in the woods, because that commune can never serve as an alternative to their system for most people, it will never be bigger than the capitalist world, at least without being forced to join it, if anything they'd be happy that socialists built their own gulag. What they're scared of is a network that any worker can draw support from, unions that their workers use to collectively bargain, within the towns and cities that their workers live, that's what an actual threat to their power looks like.
