See, but it does. The value of the company hasn't changed just because there was more stock activity. Demand causing a change in price doesn't equate to an intrinsic value of the item. Like stamps or comics. Tulips. Beanie babies.
But in the end, the price still went up, even though GameStop is still the same company it was on Monday. All because people willed it to be worth more.
What intrinsic value does any asset have?
