Yep. It will be very incremental. Along the way you can’t buy more than $X of food or $Y of fuel. Your doctor “advises” you to comply. Then you can’t get any health care. Your bank won’t lend you money. You can’t get a mortgage. Your outstanding loans are called. You can’t buy guns or ammo.
It is all so obvious.
IF it ever really comes to pass, we can blackmarket around it
