On a much smaller level, some car races/events (the Gambler 500 - or offshoots, rather, the Gambler doesn't enforce) use a similar model for fairness.

One of the competition rules is that you're only allowed to spend $500 on the vehicle. The way it is enforced is that you surrender a pink slip with your entry, and at the end of the event if someone else wants your vehicle for $500+, they can buy it.
