Beyond the Stripe payments announcement this week, it might be less known that they already support fiat on-ramp (eg buy ETH with credit card on Metamask via Stripe).

This is even more powerful with Stripe Link (https://stripe.com/payments/link) which pre-fills payment info for those already in the Link network.

imagine a debit card that you fund with assets that you mint a stablecoin against to spend, rather than sell the asset itself. 

then you earn points like a credit card, and the points function as endogenous collateral with TVL - Stablecoin supply / points supply deterministic value
