It seems to me like a social score system is a direct upgrade to this in certain ways: participating in undesired behaviour will cause you headaches you cannot really solve with money. Too bad it "naturally" slips into mass surveillance, but restricting privileges would be a great alternative to reducing the ability to take care of necessities for you and yours.

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.
