> if the problems of ledger privacy could be solved
Big if, still hasn't been solved. Monero is a sybil honeypot chain for larps that's less private from the state than Bitcoin simply because the anonset is shit and attracts lazy dumbs that can't do proper UTXO management.

Is there a decentralized ledger, near-costless verification, and most importantly, a deeply liquid market for this? Yes you could clone Bitcoin bit for bit today and have an equally scarce base unit, but the scarcity of the conception and resultant gravity-well cannot be replicated. Every shit-chain reinforces this, shit-chains are not scarce.
