Regarding the idea that we will all get COVID19 no matter what, I ask you: did everyone eventually get the Spanish Flu? The Swine Flu? Nope. These things, at least in their deadly forms, don't survive well over the summer for some reason, and typically disappear (mutate into a relatively harmless form) within a couple of years.
Viruses are a kind of a parasite, i.e, they depend on living hosts to propagate their species. The more severe they are in terms of symptoms, the less they are doing their own survival any favors, since dead people, and people sick in bed, don't spread them very efficiently (nor do people who stay isolated for fear of contracting it). So mutations that are less harmful quickly displace forms that are more harmful.
The best case scenario from the perspective of a flu germ is to mutate into something with symptoms like the common cold, so people who have it remain up and about, and alive, so they can efficiently spread it around from host to host without killing them or making them bedridden. Having the effect if being deadly to its host, in other words (from the perspective of nature), is a fault in a flu virus that nature seeks to correct, as it is non-survival-adaptive from the perspective of the germ.
virus are very delicate, too dry and poof, they denature (they don't die like people) to much sun light, particularly in the UV range in at direct summer angles and longer exposure and they get sunburned (just like people)
