See, I think copyright has value, I think it has just lost sight of its original goals and intentions because corporations (which never die) have vested interest in copyright being as long as possible.

According to the research of Rufus Pollock, optimal copyright term is between 15 and 38 years. This provides a range that the majority of copyright holders will make the majority of their income from copyright on, while also promoting the originals goals of copyright which was to allow artists to support themselves while also promoting creation of new media. The majority of copyrighted works only have a real shelf-life of 15 to 38 years before people aren't really looking to pay for them, so why should we have copyright that exists beyond that when most will have already made all the profit they will ever make from their works within that timeframe.

I personally think UBI is a pretty weak replacement for copyright. UBI shouldn't wholesale replace markets but rather be a safety net for people who are struggling and need a basic amount of support to reasonably survive.
