Everything, if people refused to pay the silly prices then nvidia wouldnt sell them at said silly prices as there would be no market for it at the price point.
Simply...
if people willing to pay stupid price = Seller can sell at stupid price
If people not willing ti pay stupid price = seller will reduce price
