Well I tend to use the moniker Mutualist or simply "Anarchist" (without any adjectives) to describe my views.
My one grip with Libertarianism isn't really with the ideology itself but many of the followers of said ideology. You see I have a problem with what Roderick Long calls "Left-Right Conflation-ism" and Kevin Carson calls "Vulgar Libertarianism".
An example of this would be how some view modern day "Corporations" who buy political power. Those institutions are not legitimate. Their wealth was made by way of utilizing means not accessible to any of us. They also tend to be safe from Market competition due to regulations they've purchased. Simply chalking it off as "well they did the best they could under the current conditions" does not cut it.
Their wealth ought to be stripped from them, as we do with bureaucrats and others Statists, the moment Freed Markets takes shape. They are enemies of Liberty and Freed Markets.
I agree Corporations are in the same league as Governments. Same abuse of power when you get to the depths of it.
Sure, but only to an extent. I can walk out of walmart without spending a dime. Try "not spending" on sending other people's kids to school and paying those public teacher bureaucracies. See how far that gets you and if you don't have men showing up at your house with guns taking your house from you because you "owe" them.
I don't see any walmart cops grabbing people off the sidewalks and dragging them into the store because they "owe" walmart for shelving and stocking all these products on behalf of the public.
