This has probably been many times but as an anarchocapitalist i would like to know the following?
Why not simply advocate anarchocapitalism and start an own "legal-system" that follows syndicalist teachings. There would be two advantages in your favour. 1) Because syndicalism is so great for the worker, every worker would be lining up to join your syndicate to leave the greedy capitalist-opressors. 2) Noone would have to be in a syndicate if he didnt want to.
Really, why just not start a syndicalist legal system? If its paradise on earth then everyone would see it and join you!
