Comment: It's "just" a price control.

It goes like this every time.

Inflation
Price Controls
Rationing

Next step: rationing.

All it means is they are printing more money than they can finance. Sound familiar?

What comes after rationing in what remains of the "Free market", in this case the grey or black market?

Bartering
"Hoarding"

However, in the US DHS already has anti-bartering and anti-hoarding laws on the books as HSOs that's right a subsdiary power of EOs to be invoked during an emergency.

And after that people who turn in their "hoarding" or "bartering" neighbors will get 10% of the asset forfeiture or a bonus ration card!

That's how it works US-style! (or will in the not so distant future)
