These are very interesting insights. I had never really thought about the 12-bar blues and 32-bar ballad as being "archaic" structures in Western popular music, but that could be the case... Never underestimate the nadir of culture we are experiencing as education of the masses gets reduced to "whatever your property taxes can fund."
As harmony, and eventually melody become DE-accentuaized as musical elements, we are stripped to bare rhythm and rhyme ... So LONG culture as we know it !!!
