Sounds like they have some common sense, it's not rocket science. You use or lose it.
I think one of the problems with trying to cure the sniffles is the bug only needs to mutate slightly to work around the cure. So then we attack that bug and again it mutates and so on. Meanwhile our immune system is not being challenged and as a result it's not evolving to fight the new bugs.
Bring in the quest for profit and the situation gets even more complicated, now we don't want to kill all the "bad" bugs as it'll also kill our income source. This may not be the case but it is possible...
COVID is only another organism on this planet that's trying to survive and multiply, it's no different then all the other creatures here. Just as the planet is our host, we are COVID's and millions of other viruses and bacteria's host. One thing we should take from this is when we die we are no longer a viable host to COVID, if we kill our habitat it won't be a viable host for us.
