Unfortunatelly when the good in question is food, it's hard to apply law of supply and demand rationally. Everyone needs food to survive in a matter of every few hours, at least. Therefore, there is a constant unstoppable demand for it. Moreover, it's not that simple to produce your own food if you don't have the necessary tools and enough space, besides having a central authority controlling the flux of food coming in and out, so the supply is really limited. This is the recipe for disaster, and unless citizens find a creative way to bypass the government's overcontrol, there is nothing to do besides paying a high price to survive or starving till death.
I think the prices of goods and commodities, even food items being influenced by the forces of demand and supply is rational. If a demand for a product is constantly increasing over time and the supply not being able to match it, there would be an increase in price. It’s only logical.
You also actually don’t need a space the size of two football fields nor the latest farming equipment to plant foods for personal consumption.
This doesn’t diminish the importance of food but It may surprise you that a well hydrated human body can survive for about two to three weeks without having anything to eat.
In addition to this, Inflation makes it worsen since fiat value decreasing overtime due to it’s unlimited supply so the increase on the goods price double or more in addition to the scarcity due to the law of supply and demand.
this is why even there’s a balance supply and demand in the market, The price keep increasing every year due to this fiat shit that cause inflation to everything since we are exchanging all our goods to a piece of paper that doesn’t have real value backing it but only trust.
