Other issues with cash:
-Can't transact instantly with anyone on the planet.
-More difficult to verify authenticity on-the-fly.
-Not as easily divisible (Need to carry specific denominations and change)
-Can't trustlessly exchange for crypto (no atomic swaps)
-Can't have multiple people with simultaneous ownership and control over the same cash (multisig)
