It doesn't solve the problem that people want what other people want. In a "post scarcity" world we will figure out how to make certain things scarce and more desirable. Then people will start gaming the system to try to acquire the more expensive/scarce items. Some will even make it their life mission to acquire the intentionally scarce items/experiences. Basically, the same situation we have now.
