Interesting issue. I wonder if it would be possible for a country to set up an extremely long copyright term (with a huge administrative fee) that would have to be respected under US law (and other adopters of the treaty).

I'm sure many music/movie studios and authors would gladly pay $100K to copyright each of their works internationally for 500 years...

Creative thinking, but I'd have to disagree with your conclusion. The present value of the additional years of copyright would be very low, especially taking into account 1. the probability that the work will still be a source of value 100 years (not the exact number, but for the sake of argument) in the future and 2.The possibility of changes in the local jurisdiction or US law over that time.

Your idea would mean paying 100k for the possibility of receiving some additional value 100 years in the future. The first 100 years of value are already protected under US law.
