Why more importantly? For an airborne pandemic with very a long incubation period (if memory serves me right up to 2-3 weeks), lack of symptoms in many cases, preventing the spread is the number one priority on the level of a city/local/central government.
Quarantines and lockdowns are good old tested ways, but infeasible for prolonged periods of time. Having everyone wear a mask and drastically reduce the spread was such a no brainer I never understood all the panic around it.
