It's math that requires an obscene amount of compute. If it's possible to make DRM chips that don't let you play pirated movies and GPS chips that shut down when going too fast, then I reckon it's also possible to make GPUs that shut down when they encounter anything that looks like a transformer. The problem is regulatory, not technical.

It doesn't require obscene compute though. I can run a model on my macbook with 48GB of RAM that is roughly comparable to Sonnet 4.6. A year from now the same machine will be able to run much more capable models.

I would agree there are sound regulations needed, but banning certain kinds of math is not it. (Your DRM example is particularly unfriendly to your point in this regard.)
