It's kinda wild that you don't need to be a professional engineer to store PII. The GDPR and other frameworks for PII usually do have a minimum size (in # of users) before they apply, which would help hobbyists. The same could apply for the licensure requirement.

But also maybe hobbyists don't have any business storing PII at scale just like they have no business building public bridges or commercial aircraft.

I'm wary of centralizing the powers of the web like that.
