Is there a graph showing global percentage and total value of utxos which have become unspendable eg tx fees > market value ? Is that about to become a massive issue if tx fees go x10 or x100 and opening lightning channel becomes prohibitive ?

Would there be a way to transform / mint them into bearer instruments ? Does cashu / fedimint possibly help there ? Could a custodian issue physical notes backed by real but unspendable utxos?

If the minting has a tx cost then it’s time sensitive to mint before minting cost exceeds utxo value.
