> Start by legally compelling companies that trained on unlicensed data to either (1) license the data, (2) publish their model, or (3) destroy their model.

You are lost in an imaginary world where everything is simple and has no negative consequences. First off, there is NOBODY who has that power over all the companies in the world. So immediately you are creating an imbalance between companies and potentially destroying your domestic industry; with long term negative consequences for the people you're supposed to be protecting. Secondly, you might be creating a situation where it's impossible to ever create a competitor to those companies who are already entrenched monopolists, potentially even making it impossible to ever run self-trained or local LLM's. Also, you just unilaterally made it legal to publish all copyrighted work (since that's what you believe their model to be) to the general public, presumably in a way that can be used by everyone; further eroding copyright law in one fell swoop. You've completely disregarded the legal issues around what constitutes "unlicensed data", and how much is required before triggering your new law, and what that would mean for the legal system potentially being inundated. You're reacting way too emotionally and flippantly, with no apparent thought about what harm you are doing and how you might actually be making things worse, not better.
