I want to preface this response saying I full agree with this, I want something like this to happen, I am responding because of some concerns I have. The real major one: How do you verify the authentication part of the data security chain?

A PGP key alone does not authentically validate that you are who you say you are. When the source is the untrusted party, it doesn't accomplish the site's goal. It's the equivalent to me handing you a piece of paper saying "I'm John Smith and this is what I use to say I'm this" which works amazing for trusted exchanges, but when the source is "just trust me bro" it doesn't solve anything for the website owner.

Websites get around this by having trust certificates/root servers that are co-signed with the PGP key. However, we lack any system like that for personal identities. Arguably, setting up such a system would isolate most of the known internet, as it is a significant roadblock, much like how SSL certificate usage was a huge roadblock for sites before Let's Encrypt became a thing.

This setup would be amazing for logging into sites. However, it fails to accomplish what the websites that are asking for PII are looking for, which is verification that their user is who they say they are, and not a random third party.

To reliably use this setup, we would need something similar to Let's Encrypt, but for user identification. The issue with that is it would become the de-facto attack vector (for both law enforcement and criminal parties), and that site would need to require PII to address the biggest concern on these sites, which is that you are who you say you are, and not Jo Smo or a bot looking to harvest data. Additionally, as mentioned earlier, a massive retraining of the internet would need to be done, which would mostly affect non-tech folk.

I am hopeful that an easy function that won't violate users privacy comes out, but I don't think the two topics are compatible sadly
