You are not wrong, but I'd argue that mutable ID methods would be worse. Ok, context and perspective will matter a lot here. If you are wanting to hide from authority then mutable id sounds good. If you are wanting to "know the history" of a person then mutable is bad. In our social contract the "inability" to change id is baked into the way be behave, and the consequences for bad behavior. Equally there are lots of good reasons to be able to get a quick history of say a prospective employee, loan recipient, tennant, supplier, customer, and so on. If I can apply for a new Social Security number every month/year then that number does become useless as a form of id. But it would then just need to be replaced with something else. Too much of what we do is predicated on our historical behavior. Having a 12-month limit on identity would break, well, just about any kind of contract. And in most contract situations uou most definitely want to know "who" you are contracting with.
