It's a good question. I think money has to be based on truths. No manipulation/unfair advantage/sleight of hand.
As soon as there is manipulation in money things downstream end up distorted.
Truth ...
That is true. Blockchain is the best ledger. But I suspect that reducing the block rewards for miners to zero is a mistake that will harm the security of the chain and reduce incentives to invest/innovate. They perform a service for the store of value but will get the rewards only from current transactions. That feels wrong. The inflation from mining should help to motivate investments. Why should inflation be 0? It could be greater 0 or negative (by burning a part of transaction fees). 0 is a nice number but why is it the best?
