You were the one proposing the laws that harken back to the idiotic central planning policies used by the Soviets. No one knows what demand actually is until it's measured. The market price is what automatically adjusts to bring supply and demand into equilibrium.
If you don't allow that you invariably wind up with a lot of companies that overshoot their estimates and have a lot of excess inventory that no one wants and that's not good for anyone. Never mind the rest of what you propose requires so much corporate or government intrusion into your life that you'd be immeasurably lucky if that's all it was used for.
Also, stop for a second and apply some common sense to what you're proposing. Earlier this year there was a shortage of toilet paper due to people overbuying and stocking up which perpetuated the behavior even more. Should the companies that were manufacturing it be prevented from releasing any new product until they could satisfy this new frenzied demand? Do we need government appointed toilet paper accountants to make sure no one is buying too much? Just let prices increase and naturally mediate people's behavior.
Exactly. Such selling policies would involve so much government monitoring, that it would simply do the opposite of what PSOlord wants. It would hurt competition, innovation and ultimately the consumer.
Only companies with the deepest pockets could survive such business practices as any company would be constantly over producing as it is impossible as you said to know exactly know the demand on the market. This would causes an over supply which would cause prices to collapse and kill companies that were forced to stop selling until supply was accumulated by ceasing cashflow, forcing companies to swallow up depreciation and for sellers or producers to eat any losses from any unsold card. This would have an effect so that only a single company can exists(the one that can eat these losses for the longest). We have seen this already during this pandemic with lockdown of businesses killing small companies first. Forcing a company to stop opening and selling while forcing to spend extra money can be tremendously expensive.
It would be a disaster for Nvidia and AMD if they were forced to stop selling cards for 6 months to safety build up enough stock for the market. If in 6 months the pandemic is over and demand for videocards fade, you have recipe for disaster brewing. When you have a tremendous amount of inventory, you have the potential to eat a tremendous amount of depreciation expense. Combine this with having no cashflow for 6 months because you were forced to stop selling which would be hundreds of millions if not billions in expenses accumulated(combine cost of goods sold and R and D/business expenses) and you basically left with a situation where companies with the deepest pockets can survive only. Forcing such measures would kill companies until monopolies are left.
Monopolies are bad because even with governments controlling pricing, a company must find ways to make money which means lowering expenses which comes at the cost at spending less on R and D, loss of jobs and more derivative products like the various lake products coming out of intel. We might gets cheaper products but if products are 5% faster every year, value worsens for consumers in the long run compared to the system we have in place now. E.g performance doubling in 16 years at the same price vs what we have today.
