Many of them have to be cleaned after each use or replaced after each use. Because of that doubt, other measures have been taken as well by governments.
Masks alone might not be enough. That doesn't mean all measures taken by governments do any good. In the case of South Korea, the schools closed at just the right time for a vacation, which shows up clearly in the case data when you delay for the time it takes for a newly infected individual to get tested and for the test to come back. The South Korean government wisely extended the school closure. However, there's no evidence their massive testing program helped, though I doubt it did any harm, either.
Meanwhile, there were other voluntary measures as well. The South Korean people stopped going out as much, and switched from eat in to takeout on their own.
