Expiring Money

Notice that they did not say the word "cryptocurrency". Despite any robust system that would work for these use cases being such.

I assume this is due to the poor reputation of cryptocurrency, lack of understanding of what it really is, and to a lesser degree a slight preference for trying to build centralized smart money which makes it easier to maintain existing centralized power.

Aside from the purpose described here, hoarding/accumulation beyond a certain limit should also be discouraged/eliminated for all kinds of assets using a mechanism similar to expiring money. Any unused asset should expire

Why not just tax capital gains and interest payments more?
