"Proof of Work" is the realization of Marx's Labor Theory Of Value.
Bitcoins are a commodity, not a currency.
You mine them, you don't -counterfeit-, I mean, debase, I mean, print more them.
They have INTRINSIC value.
It's pure monetized and mathematically calculated labor.

Robbing the capitalists by bleeding their value into our new, SOCIAL Peer-to-peer decentralized
anarcho-socialist utopia? Where people are 'taxed' a network fee, in order to support the system?
Sounds pretty socialist to me.
