If it's a test you run yourself, it's absolutely true that some people won't test, or will test positive and lie about it.
As long as a large majority of people do the right thing, and report / self isolate if positive, a few people cheating here and there probably won't be enough to affect the course of the disease.
We need to remove incentives to cheat. I don't see much stigmatization of people with the disease in the USA, so that's not a worry. The biggest problem is economic, lost paychecks. We should probably require companies to allow sick leave for coronavirus, and have taxpayers pick up the tab for now.
