Sometimes the government has to do what it has to do to protect the rest of its people by being very strict. The health of its people is more important than personal freedom. Pretty much one person's irresponsible action can lead to the the sickness and deaths of a lot of people. For people who don't know virus, the more the virus spreads, the more likely it will mutate. The more it mutates, either it gets stronger or weaker. And that's what's happening now. There are now many strains of the virus. But based on some new findings about how it behaves, there is a possibility that it is not getting weaker but becoming stronger. So there is a possibility that by the time a vaccine is developed, that vaccine is not effective anymore since the virus has already become much more powerful than the vaccine. This is the worst case scenario. In most cases, it is better to err with caution.
