I don't understand the distinction you are making. If you have a massive excess of demand ready to pay any price, and a limited supply, of course the sellers will take advantage, that's how any market works. They can do that because of the lack of supply.
Over the long term demand will rationalise and supply will adjust. But in between there is a squeeze, and the right price is the maximum price buyers are willing to bid for the limited supply. Sucks for other buyers, on the other hand it ensures demand destruction, i.e. that the limited supply goes to the buyer who need it the most, other buyers will delay their purchase and do with what they have.
