> Right now a kid can go download an Abliterated version of a capable open weight model and they can go wild with it.

Is the reason to ban or block free open weight models that you're worried what kids will do with them?

I'd imagine the economic case to be made is that the Western AI companies will ultimately not be able to compete with free open weight models. Additionally, open weight models will help to spread the economic gains by not letting a few monopolies capture them behind regulatory red tape.

Finally, I'd say the geopolitics angle of why open weight models are better is that if the West controls the open source software that will power it will be able to reap the benefits that soft power brings with it.
