What’s a fundamental non-currency infrastructure affordance of blockchains that can’t be delivered with web2 or older stacks easily?
A near-example is NFTs bought on one site showing up on another, which you can’t do in web2 (closest is walled garden/game badges).
Things like this but more infrastructurey in flavor, and neither finance related, nor fun and games. Maybe like DeFi for nonFi things?
