Ask HN: Why doesn't HN support post or account deletion?

In addition to the fact views can change, or someone might have other concerns. (Ex: maybe they didn't plan for being forced to disclose their social media at the border when making legal political speech), doesn't GDPR require it (at least for EU citizens)?

(It's my understanding that HN comments are permanent, absent a short edit/delete period and accounts aren't deletable, if either is incorrect please feel free to let me know in the comments :) )
