i advocate anarcho capitalism

but i see no problem with people forming communist groups or worker run factories or anything of the like as long as it is voluntarily done. that being said, i have a problem when people want to force their govt and econ beliefs on others that do not want them. any violent revolution or forceful action is immoral. forcing people to live in a communist society is unjust. on the same hand, forcing anyone into a capitalist society would be unjust as well.

I think you've reached a conclusion I can agree with, but I have one problem.

What about the carrying capacity of our species that we have increased through things such as the agricultural revolution the so called "Green Revolutions?"

I believe, as a Marxist myself that this situation has placed us at a "no turn back" point in human history. We can't just ditch capitalism it seems, because it is the system that has created the genetically modified crops that have increased yields and greater resistance to diseases. It is the capitalist society that has provided infrastructure and maintains that each individual to a rough extent has access to medical care.

How would we go about undoing this without radically transforming the already pre-existing power structures left from capitalism?

Perhaps a depression or a large national disaster?
