That its difficult to do today, you need to manage your own private key infrastructure. So it becomes reserved for a few important things, like a digital ID. What if it were easy and dirt cheap to make a provable claim about anything, in seconds, with a fraction of the infrastructure cost? Like "I am signed into this application". Or "I have received a covid vaccine", or "i authorized this payment". Theres probably a lot more, my background is in identity so those are the ones I know. Yes you can do those today but they all carry significant cost, and as a result there are significant moats around established players. Just like Letterman asking "why do I need such information, have you heard of magazines?". Its true, magazines can do that. Just like PKI can do all those things.
