Thanks that’s very insightful and I’ll amend my position to 15 years 5 may be just a little zealous. 100 year US copyrights have been choking innovation due to things like Disney led trade group lobbyists, 15 years would be a huge boost to many creators being able to leverage more IPs and advancements being held in limbo unused or poorly used by corpo entities.

You don’t have to stop selling when it becomes public domain, people sell books, movies, music, etc that are all in the public domain and people choose it over free versions all the time because of convenience, patroning arts, etc.

You don’t have to stop selling when a book becomes public domain, publishers and authors sell public domain/commons books frequently, it’s just you won’t have a monopoly on the contents after the copyright expires.

Copyrights should have never been extended longer than 5 years in the first place, either remove draconian copyright laws or outlaw LLM style models using copyrighted material, corpos can’t have both.
