It's not ideal, probably it will create further delays, but it would put small business on the level playing field with the big corporations when it comes to orders.

Maybe such surge of demand could incentivise MCU manufacturers to secure more fab capacity.
State could also make scalping illegal. For instance buying MCUs with a sole purpose to hold on them and then resell at inflated price would be illegal. This could be done by setting maximum margin someone could ask, that should be no higher than Mouser or Digikey have. So anyone selling MCUs at 10x the price would have them confiscated and get fined. Foreign online stores that facilitate such sellers like Aliexpress would risk being sanctioned and banned.
