Yeah I get scarcity within a community, theres so many examples of that from pokemon cards to beanie babies, but you're always relying on a centralised entity and community consensus. If a new card is made does it damage the value?

does the community not decide the premium?

Going up in value is one thing, having liquidity to access is another, the card is now worth what Post paid for it, doesn't mean its what he can get for it by the next person, there are only so many rich people interested in that niche
