GENIUS led to a sea change in usage, perception, and acceptance of stablecoins. Don't understimate the effect of passing CLARITY on all things payments and markets.
I don't understand the premise that "agents must use stablecoins."
Why can't an agent remember the 16 digits of a credit card?
Sorry maybe I'm a payments n00b. Stablecoins have a lot of great use cases, but ecommerce shopping is pretty well optimized already for cards.
