Frustration

I have no idea. I haven't found it super difficult at the very basic level that I know, but I don't know much

So you understand why price floors/ceilings are a terrible idea and don't work?

yeah, because price is a free market mechanism to show producers what consumers value, and consumers what the producers need to continue producing. if producers can't raise prices to compensate for higher costs and/or lower demand, then they'll stop producing, because it now loses them money to make and sell the product. it's simple supply/demand. and then if that happens, no one gets the product.
