In practice there really is no valid use case for a blockchain. Sure, the idea of a distributed, trustless ledger is clever. But in practice the only people able to run full nodes and do transactions are the big stakeholders, either in terms of PoW mining pools or whatever proof of stake model is “totally coming soon”.

The transaction fees and excruciatingly small transaction throughout make on-chain transactions impractical for ordinary transactions, so now you’re back to running transactions through centralized exchanges, which undermines the security of the trust model.
