No, what will happen is some people will get meat for the week in their shop, and some will get none.
Imagine meat is like toilet roll, one day a family turns up late to get their food from the store and there is no meat left for them.
It's better to avoid situations like this by trying to convince households to eat more alternatives, than to leave some households with no meat at all or let meat queues start etc.
A-hem. Command economies and central planning are interesting like that.
We live far north in Norway, sunlight is relatively scarce through the year, which means Vitamin D deficiency is a concern.
But what is also a good source of Vitamin D? Fish!
> This prompted Mikoyan to issue an order on the “introduction of a fish day at public catering establishments.” It didn't have to be Thursday, but from that moment on, factory and other canteens began to serve fish one day a week
(emphasis mine)
Encouraging weekly fish-eating habits is also a mechanism to ensure that you have a healthy national fish industry, that you can dial up as soon as you need it.
This is something that modern [especially European] nations seem to have institutionally neglected or forgotten.
By importing all necessities and instead focusing on exporting services, you put your nation and people at risk from any such crisis.
In the early months of the Covid pandemic, most developed countries saw a toilet paper shortage. Not due to supply, but due to consumer behaviour.
If anything, a real or perceived shortage tends to cause consumers to behave less rationally, not more. Markets don’t self-regulate well in these circumstances.
Maybe, just maybe, I am really going out on a limb here, the USSR did not have prices for things that reflected the relative scarcity of items.
But I suppose there's another possible reason. If you can't give people what they want (meat), give them something else (fish) and try to convince them they do want it. If you can actually pull that off, then maybe it makes you look better and/or makes them feel better.
