Some people argues that, but that's not how scalping works because it first chokes the supply to create a fake demand. The scalper listing prices don't represent the true price on supply-demand curve had there not been artificial meddling through published MSRP, but merely how forcefully they managed to choke the life of the product.

They buy up ALL the stocks. Then puts them on auction sites after supply had hit as close to zero as possible. That's not how economics work by the books.
