Good point about protein folding. Right now it's simulated with classical physics on conventional computers; quantum chemistry algorithms on classical computers scale too poorly for use with macromolecules. But a many-qubit computer could be excellent for that and other molecular-scale calculations. (Not that getting good protein folding models would cure cancer, but it's reasonably likely to aid biological research.)
