I like that theory, but TFA doesn't really advance it. Among other things, TFA argues that commercially powerful interests like record companies deliberately fractured rock and roll's racial integration into segregated genres. I don't think "geeks, mops, sociopaths" covers this kind of intentional, external crackdown on a subculture.
The way I read the article, the actual "crackdown" was motivated more by financial than racial reasons by the record companies. The racial segregation was just collateral damage from that process. Doesn't that fit super neatly in the "sociapaths extracting value from a subculture at the cost of internal coherence" part of the theory?
