Those are all temporary events and circumstances.

If the market is big enough, competitors will appear. And if the margins are high enough, competitors can always price-compete down to capture market-share.

Competitors will appear? You can't build a DRAM production facility in a year. You probably even can't in two years.

Also, "price-compete down to capture market-share"? Prices are going up because all future production capacity has been sold. It makes no sense to lower prices if you don't have the capacity to full fill those orders.
