EU already has this with the GDPR. Only limitation are retention periods required by law, like employee data needs to be kept for ten years in Germany for example, but for the duration whoever has the data must block it from being processed for anything but the legal requirment, as that becomes the legal basis for processing (storing in this case) and no other uses are allowed until deletion.

Only applies to EU citizens though plenty companies have implemented straightforward ways to delete an account for everyone.

The US and the USSR engaged in a race to have the most nukes. After the fall of the Sowjet Union international treaties were put in place to reduce the number of nukes in both east and west.

Don’t quote me, but if I remember correctly, at the height of the cold war, both sides had more than 12.000 nukes each.

Humanity had enough fire power to delete the entire globe roughly 40x over then. Why? Because bigger is better.
