A single person can do whatever and no one gives a F. As to the health authorities - they are acting responsibly. It is in the best of interest to delay, manage and contain the virus spread, even though it's probably impossible to stop, because no country is in such surplus of medical resources to be able to admit hundreds of thousands of patients with severe respiratory issues. And the collapse of some local medical systems will incur mass hysteria which will make managing the crisis really difficult. So distributing the infections is really, really important, and will save many lives.
