In a true anarchist society, what stops the very same people who are committing human rights violations now under the guise of government from doing the same thing as freelancers?
People in government have a lot more power then those who aren't in government. In anarchism, everyone would be on an equal level. Therefore a "freelancer" wouldn't have the power to do the mass-scale human rights abuses that they would if they were in government.
but also... I'm not necessarily an anarchist nor am I against anarchism
