That's a very naive view. While illegal content might "only" get you incarcerated in most of the western world, it will get you straight up killed in a lot of the other countries.

This doesn't stop just because the technology is unable to delete anything.

It does stop. When a technology becomes important, countries who forbid that technology miss out. The tech migrates elsewhere, taking talent with it. How many times have we seen that pattern?

You can try to make Ethereum illegal if you want, but it'd be a tactical mistake. Ditto for unbreakable encryption.

In fact, explain why it makes no sense to make unbreakable encryption illegal. Show your work. I suspect the same argument you'd use for that will apply to this.
