Crytocurrencies require a log of ALL TRANSACTIONS, not just the so called utxo set...
If one can form a consensus over one set of data, peoples favorite bloated log, which is in effect one big pile of state, then one can perhaps form a consensus over any other set from it, eventually among other possiblities, mining deltas to move a UTXO state db forward, potential db distribution and update mechanisms, etc... all under some form of consensus, facts of formal verification, etc. To claim Satoshi Genesis Blockchain whitepaper is only way to do things, that there are no other ways to be found, or proofs proving no others, is really quite ridiculous in such early days of research where no one knows much about what is or isn't possible. All possible within physics. People with head locked in sand will never find them.
