Isn't there the inherent risk that the anarchists who overthrew the status quo could themselves become the status quo? [...] It would be the same issue that communism has had in the past. Everyone is equal, but this guy is going to be put in charge to make sure of that. And then he collects more and more power.

The issues that communists have had in the past are rooted in what's called "vanguardism". This is essentially the idea that if a communist party gains control of the state, it can use the state machinery as an implement to conduct the revolution. Once the revolution is completed, the state would theoretically become redundant and dismantle itself.

Unfortunately, hierarchical institutions are self-preserving, and generally incapable of purposefully destroying themselves. So the communist state eventually becomes self-interested and oppressive.

A movement with a culture of resistance against hierarchy, and a goal of dismantling oppressive institutions rather than utilizing oppressive institutions, should not be susceptible to such failures. The AFAQ has a great section called H.5 What is vanguardism and why do anarchists reject it?
