Or, an alternative, and hear me out, maybe this could also be called "an economy"

Confidence in crypto will go poof when there's a big enough run that the measly 7 transactions per second can't keep up with demand. We just haven't seen a crypto bank run yet. The $100 / transaction is nothing compared to what it could be. When that happens "stable" coins will lose their stability and the smoke and mirrors behind audit-free coins will collapse. You couldn't pay me to hold crypto.
