That’s the reason we have to still use fax machines right?
I know there are ways to do encryption like PGP on your message directly or I think email sent over TLS? But that isn’t the default right and that’s why I can’t send a picture of my license to the insurance company directly over email?
I’m definitely not advocating for that. Just for “official business.” Chatting with your friends or something, use matrix, signal, telegram, gpg, whatever you want. Signing documents or sending documents to your bank? That’s when you need the government CA. Basically anytime you would normally use your ID to identify yourself.
