If you're familiar with aircraft you're familiar with the concept of a stall... that's where the plane loses speed to a point that it stops generating lift and falls straight down out of the sky
Velocity of money in a fiat system works the same way, this is why the fed is trapped and fiat systems are unsustainable... it's a gross misunderstanding to think you can apply fiscal discipline to it. It also underestimates natural deflation's ability to keep the system going in the face of printing and false rates.
"You can't taper a ponzi", if they wait just a little too log to cut rates or print, velocity stalls and that's the end of the system as we know it. That's the no landing scenario. Wall Street banks are the stall warning system.
Bitcoin is here as a parachute, not to land the plane.
