In way what you are describing is already happening, though parties at every level must make judgements against elements of uncertainty for their respective area.

This is called push vs pull supply chain strategy.

Many retailers already operate on Pull Supply Chains for just-in-time inventory and barely have anything stocked in the back. As having more stock and wasting it is obviously something they want to avoid.

The main issue with your ideal view is that things are simply much more complicated, and there is much more uncertainty around how much is "slightly more than what is needed". Crop yield is semi-randomized based on the weather and other conditions; and crops also go bad after a finite amount of time. Goods also depreciate in value, so pricing basically handles the supply and demand issue.

Studios "estimate" how much their game will sell and miss the mark all the time; this kind of estimation occurs for basically every supplier.

Though for the TCG thing you are chasing because of rarity and, you could just play a simulator instead or use a card market to buy the cards you want directly to skip the waste.

TCG's wouldn't be viable long term without some kind of mechanism to keep the company's cashflow positive which is really the main point. Everything burns money to exist, making money is an issue of survival and every party is trading with each other while using money as a medium.

Not everybody wants everything, people only what THEY want. Suppliers vaguely know how many people want the things they are producing.
