"As a very flattened retelling of history, it was only with the boomers that we reached the tipping point on how people started to think about copyright (Copyright != Attributed Authorship). With them, a majority started to believe in a world where the human history they consumed was a gift from the past, and that what they themselves create must be bought by future generations."
I honestly just don't know what your are trying to say and what it has to do with boomers. Are you just talking about physical media copying of books, CDs, DVDs, etc.?
The idea that things are created because there is long-running and expansive copyright, is a story that only became the norm around 1950 - i.e. boomers.
Today any kids uploading their YT video thinks of their own copyright. This explanation of copyright as "creator protection" is a story much younger than copyright itself. Its incongruent with history or how its used today >99.99% of the time.
