That is very interesting. I assumed that false positives is generally a testing error (testing with another method or from another company would not lead to the same result). If the false positive is a result of a non-dangerous anomaly of the person being tested, then, I see how testing without symptoms can be worse.

Herein lies the real issue. Biology is a very, very messy science. So yes it could just be a testing error. But it might not be. It might be that something in your body behaves in a way that's unexpected. It might be some other non-dangerous anomaly as you cite.

We understand far more than we did say 20 years ago. But the problems are non-trivial on a scale most people don't appreciate.
