Bitcoin doesn't exactly appeal to most left wing anarchists from what i can tell. Most have some idea of taking capital from the capitalist to re-distribute to the masses. Bitcoin doesn't really lend itself to that. Bitcoin is going create a new system, I agree. But not one that's void of strict property rights.  

 Exactly, all disputes can be viewed through the lens of property rights and contractual agreements. The one moral wrong is to steal. 

 I agree, ancom is a silly ideology.
