A crypto wallet is just a random number. Literally. Everyone using wallets for identity equals everyone just picking a random number to represent themselves (and then classic cryptography allows you to prove to others that you know this number without revealing it). The hard part of this is not cryptography — that is already solved quite well. It's the human side. People forget pass phrases. Or disclose them to whoever calls them and says they're from Microsoft Pass Phrase Verification Authority. People break computers they haven't backed up. People click "Yes" on security prompts, and open random mail attachments. With private keys involved, these situations are irreversibly catastrophic.
