Im not a MWM fanboy, I just couldnt finish the video and get to your likely relevant points because it was grating, id suggest balancing out the audio a bit more next time.

As for MWM it'd be good to remember hes a relatively young guy still figuring stuff out, while I wouldnt advocate for him as a reliable source of knowledge I wouldnt be annoyed if he contributed to the socialist project I was in either, I just wouldnt give him theoritical or directional control because its clear he has some holes in his theory.
