I am sorry, if you 'reject capitaliam' but have to check if 'your employer' cares, and pay 'your landlord' and go to the same grocery store, what exactly have you rejected?
Based on what you're describing "reject capitalism" is just edgier phrasing for "not respecting property rights" (ie. expecting your employer to give you money for nothing, or for your landlord to house you for free).
Simple example - bhuddist monks, they don't take part in capitalism, they do their own thing.
Would you be allowed to build a monastery on top of a random mountain in America today? Clearly not. Force will be used to remove you.
So you portrailyal of 'anything short of terrorism is fair game' is totally inaccurate - the only way you are allowed to reject capitalism by selling tickets to a concert where you just talk shit.
