> We could even do like we do for patents, and have a relatively short term, with a one-time renewal option for creators who continue to benefit from a work and still care to keep it protected.
The US is part of the WTO and thus a signatory to the TRIPS agreement ( https://en.wikipedia.org/wiki/TRIPS_Agreement )
> TRIPS requires member states to provide strong protection for intellectual property rights. For example, under TRIPS:
> Copyright terms must extend at least 50 years, unless based on the life of the author. (Art. 12 and 14)
> Copyright must be granted automatically, and not based upon any "formality", such as registrations, as specified in the Berne Convention. (Art. 9)
Changing that to a "short term and renewable" would involve leaving or renegotiating the WTO. That is likely a non-starter.
