I think it would be impossible, not cost effective and likely dangerous to treat everyone who tests positive with antivirals. However, I do think that it would likely stop symptoms from developing in many people.
Mother who are HIV positive are given intravenous antivirals right before and during birth and the newborns are given the same drug orally for almost two months after birth. This has caused the risk of HIV in babies of positive mothers to plummet. In fact, 99% of moms DO NOT pass the disease to their babies, following these protocols.

I'm no doctor but based on some research I have seen, (gay men on PreP have lower rates of coronavirus infection) and the use of anti-virals to treat patients with severe forms of COVID, I am using deductive reasoning to conclude that the elite have the ability to obtain aggressive prophylactic treatments that no one else can (due to money, health care company protocols and risk) and thus their probability of becoming seriously ill is far lower than those of the general public.
What I have seen in several stories of people who have died or become very ill, is that they're told to go home and then self-treat, and/or never seek care to begin with, thinking this is not a big deal and only come back to the ER when it's too late to effectively treat. That is both a problem with our health care system and a problem with downplaying the seriousness of this virus.
So the outcomes of all the celebrities and politicians who become infected is NOT representative of what could happen to the average person and I am very worried that this will cause people to further downplay this disease to their peril, and the peril of those around them.
