Yeah but their freedom slogan isn't anything unique, it's the core of Liberalism. The freedom slogan works for radlibs because like Libertarians they most likely lived a middle income life, which in America is very wealthy in global standards, and they only think about the state in terms of limiting their Liberty to get what they want, or not doing enough to protect their ability to get what they want.

Their overwhelming interests (needs rather than wants) are being served by the bourgeois settler state, in the same way as the ML AES's proletariat's interests are served by the vanguard and DotP.

I think the anti-establishment politics don't really exist outside of the worker's movement to take power. All bourgeois ideology is establishment.
