Ask HN: Why doesn't everyone consider themselves infected?

What is the point of waiting for a test? It is known that the testing is not going well, chances are it will be at least two weeks for any one not showing symptoms to get tested anyways. Why wait for a positive test result and be forced to quarantine? If you can stay home, stay home and if in two weeks your not sick, you probably don't have it. I know the government says that testing people is the best way to track the spread, but personally I would rather not be a node in any sickness graph, nevermind over burden the health care system because I couldn't stay home and chill out for two weeks.
