Damn, so pretentious.
I agree with many things, in particular his sentiment about styles and "rules", but his demeanor is uninspiring.
He doesnt provide much clarity around good writing and just comes off as rationalizing his own taste.
You cant scorn popularity and accesibility, you gotta understand it and work with it to the extent that its important for what you want to achieve.
Art, history and social contexts fold in on themselves, if you're using a baroque style of writing then understand where it belongs and do something cool with it. Be conscious of it.
