It doesn't have to only be money. In person waiting time is another mechanism to allocate a scarce resource. Back in the day when # of tickets exceeded demand at a fixed price, the tickets went to he/she who was willing to arrive early and wait in line longer (ie, die hard fans). Camping out for tickets was a thing and I somewhat miss it relative to scalpers and price being the only mechanism to drive demand/supply to equilibrium.
