The whole point was to "promote the useful arts" by allowing creators SOME time to make money off their work. People would be way less likely to write a book, a news artucle, make a movie, etc if someone else could just instantly sell copies and you couldn't support yourself with the work.

But the whole point was to give you enough protections to make it worth your while.

If you can't make enough money off of the work in 14 (or 28) years for it to have been worth it, then it's not worth it.

No one has ever said "if this isn't going to give me the exclusive right to make copies for 80 years after my death, then there's no point making it". And that was the only point to copyright. Doing the minimum to allow people to realistically make new stuff.
