Again, no one here said to go get some and try it out if you have a sniffle. Your original posting argued that there was no point to testing. I think that this is a bad idea, as testing can determine risk groups and help identify likely asymptomatic vectors (i.e. Typhoid Mary).
Your statement about “no treatment” is also, clearly, wrong. If you would have said “early indications of an effective treatment” or “possible treatment”, I wouldn’t have objected.
People self-medicate all the time. Aspirin can cause hemorrhages and strokes. Tylenol has one of the narrowest therapeutic margins of all OTC pain-killers and is the major factor for acute liver failure in the US.
Planquenil (hydroxycloroquine) is available OTC in France. The retinal damage of which you speak typically manifests after years of taking the drug [1].
So, I don’t think you should sit at home until your lips turn blue, if you think you’ve got the SARS-CoV-2 virus. Better, faster tests are being developed in what seems like days. Go get tested and, if you don’t have risk factors for cardiac issues, why the heck not get an Rx for a drug that you’d take just to go to a 3rd world country for a vacation?
