This was fun last time, leggo again
I'll start with: libertarians have solid takes ~40-50% of the time and many of them just need to be pushed a step further in their thinking to turn against capitalist oppression along with state oppression. The libright-to-leftist pipeline is stronger than most seem to think it is.
Unless someone can instantly convert all of society into classlessness, then authoritarianism is unavoidable, you'll either have the authoritarianism of the dictatorship of the bourgeoisie or the authoritarianism of the dictatorship of the proletariat. I have yet to see any materially possible way of instant class abolition, so the only way out is through.
