Some good points. I think a major problem is with the word "identity", is that there are always (at least two) meanings that may or may not intersect. We have self-regarding identities and other-regarding identities. The set of things we define about ourselves that includes beliefs, intentions, secrets and so on may be (for secrets must be) disjoint from the set of things others attribute to us, reputation, observed…
> right to be forgotten 1984 had a pretty good argument why it’s dystopian to tell people they are not allowed to remember or continue believing something.
Its a good book. It should also be tempered with a little Jane Austen, about the tyranny of unshakable reputation. My take is it's the "telling people what they are allowed to do" part that is dystopian. To that extent all laws are dystopian. However we do it all the time and obtain great wider benefit. For example, bad money choices might lead someone into insoluble debt, they declare bankruptcy, and seven years later that is deleted from public records so they can make a fresh start. In reality a "right to be forgotten" is more of a right to be forgiven. Asking that people forgive and discount past wrongs is not the same as poisoning and torturing them in a basement until their minds are wiped, as in some demonic MK-UTLTRA shitshow.
