And when people start blocking the ability to pass through and whatnot, you'd just regard that as an act of aggression.

That's the problem though, I've never met someone who wasn't an an-com who agrees with that. Every non-commmunist anarchist seems to think private property is #1 and it's not aggressive if someone owns the property, as it's their choice what goes on in the property.

That's the reason I have a problem with people who identify as "an"-cap as because of machines and the robotics that are here and easily implemented there's simply no role for money or capitalism.
Unless the capitalist artificially makes things worse, like they do in this society, and then essentially "farms" everybody else, then he must make them all die in the streets as they provide no value in a traditional capitalist sense.

I agree voluntarism should be the same as what I'm saying, but most I see still think capitalism can be voluntary when they force things like private property on people who have no capital, which thus puts them in the position to work for the capitalist or die.
That's not voluntary. You need basic human needs given or the ability for someone to find it on their own, such as out in nature, but with private property that isn't really a thing, at least without "muh nap" being brought up as an excuse to enslave.
