No, you can sell less at a higher price.
It's the loss of cash flow that puts you out of business.
Any street vendor in Mumbai or Calcutta can tell you that one!
The other big problem is not being able to obtain stock. There are two reasons for that ~ 1) short supply, or, 2) no supply. In the Great Depression, as it began, folks were unable to differentiate between "short" and "no". Once they figured it out all they could do was "dump stock" at less than the price of current acquisition and hope to escape with something. The result of this practice on a wide scale throughout the economy was deflation. This, in turn, did not increase the availability of goods. Which, of course, takes us back to cash flow as a problem.
The rule is, it doesn't matter how low the prices are if you have no cash flow!
Laws that regulate prices under any circumstances are an affront to concepts of freedom. As politicians struggle to stay in power, everything will become an emergency that justifies whatever politicians believe will garner the most votes. Government taxes are the largest single item in every family's budget. Taxes are more costly than food and shelter combined. All democracies end in bankruptcy or hyperinflation. Are we free individuals or government serfs?
