I'm very confused by both of your points. The supply of a cryptocurrency is equal to a person? A crypto token is not a person so I'm guessing you missed a few words there?

How is building a competing chain to more efficiently solve a problem (high transaction fees) in a competitive market in any way "dismissing" that problem? That seems the exact opposite of dismissing a problem.

Do those new solutions come with new problems? Sure, that's true of any technology. Dynamo-based databases solved high availability and network partitionability of data but come with several trade-offs. That doesn't mean you shouldn't use Cassandra for anything.

That said, Solana is not the hill I'm willing to die on and it's hot garbage. Hedera seems good though.
