I think you might just be blaming other people for your unethical behaviour as a teenager.

If there no way to detect false positives then everyone is a false positive.
That does not logically follow.
Proof by contradiction:
I have invented a dumb test for COVID-19: I look at a linkedin profile of someone, then I lick a block of salt. If my tongue tastes salty, then I conclude they have COVID-19. Trivially, my test has no way to check for false positives. So, if ran this test on someone, your statement implies that they would be a false positive and therefore they would definitely be free of COVID-19.
Unless you think my salty tongue has magical COVID-curing powers, then even a broken clock is still right twice a day.
But to answer your question, yes, it would be statistically prudent to assume that everyone who passed your test is free of covid because the proportion of the general population who have it is less than 1% currently and your test produces a 100% positive rate.
This is a specific case of https://en.wikipedia.org/wiki/Prosecutor%27s_fallacy
I would rather live in a world where people with real psychological problems can get help and you can get high than the reverse.
Psychiatry has a rolling history where everything that was done 30 years ago is so barbarous that the treatments are criminalize, and it has been that way for a century. At what point are we going to realize that there is no baby in the bathwater?
The field of mental health is definitely in a sorry state today, at least in the US. A lot of progress is being made in terms of research and knowledge, but it's not as impactful on the practicing community as it should be.
The problem is that when I was a teenager I could walk into any psychiatrists office and leave with whatever drug I had decided I wanted to get high off for that weekend. I memorized a list of symptoms, said I had them to a GP, got a referral to a specialist and repeated them there again. If I started on Monday I could get a prescription by Thursday. Having talked to "problem" kids of friends it that's still the case today.
I never took the field seriously, and until I became an adult didn't realize anyone else did either. I just thought of them as legal drug dealers with good quality product, but not as fun as the unregulated product you could get on the street.
Imagine my surprise when I found out people actually took prescriptions for decades at a time, something that is as horrifying to me as drinking yourself to sleep every night because someone told you to.
