I was more thinking of a kind of "Right to keep at least a basic service"... a bit like a kind of GDPR ANY identity provider (meaning email, facebook, ...) can terminate any account BUT MUST provide a temporary (maybe 1 month) minimum service (maybe only replying to incoming emails for example, with a cap) to allow identity migration out of the platform... because identity can't be owned by anybody. It doesn't need to apply to ANY website, ONLY to website providing some identity service (like email or auth provider). And this could be quite a simple law. It wouldn't forbid the website to cancel accounts, only would they have to give enough time and functionalities to properly manage the cancellation and its impact on the user digital life
