Why isn't just making sure the expected private key didn't get wiped a good enough way of making sure it's not modified?

Okay, how about that it destroys the secondhand CPU market? Once you use an AMD CPU in a Lenovo computer, it blows e-fuses to keep you from ever using it in any other brand of computer: https://news.ycombinator.com/item?id=29958247

What's to stop someone from extracting and restoring the private key?

Sure, then how about addressing that issue rather than proposing to outlaw an entire mechanism entirely? We have a lot of things that can be misused, but (generally) only in extreme cases do we outlaw the tech itself. More usually, we have laws targeting the misuse of the tech.

Isn't the whole point of these chips that you can't extract the private key, so that if it gets wiped, it's definitely gone forever?

But this particular technology doesn't seem to have any legitimate uses.
