I don't think they do, there are indications that people don't get as strong or lasting immunity as people hoped and that it causes permanent damage (to lungs, brain maybe heart & kidneys too) to people that get it, this includes people that have mild symptoms during the initial course of the disease. This means it's not the purging the weak and old, it's damaging the workforce and it's ability to work and produce surplus, they will get less profits the longer this goes on. Consider the strain found in the Americas are more infectious then the ones found in Asia, which means it's still evolving.
Objectively speaking if you interfere with the efforts for containment you are siding with the virus against humanity in an evolutionary battle. There are now sufficient numbers of people as well as ways for rapid global transmission of viruses so that biological immune system of homo sapiens will not be able to counter-act this, we will not be able to adapt on a purely individual basis against this. Keep in mind that these viral outbreaks are likely going to keep happening. We will have to build immune systems additional to that in the body. This will have to mean government's will have to keep doing the temporary shutdowns during infection surges and it will mean looking towards early warning system, extending hygiene infrastructure and so on. Obviously if bio-tech improves the ability to produce vaccines, so that people get faster "anti-virus updates", that would work, but where is this magic bullet going to come from, it's not like we have a recipe that can be put into production, every outbreak of this type will require a new dedicated effort to produce a vaccine.
ihmo: countries will compete for having good anti-viral procedures, and it seems like crisis management from external shocks like this will become a feature for this century. Vulnerability to interference by stuff like these investor-dispute-lawsuits might quickly become an existential liability, there's other crisis than viruses in the making that will not respect capitalist economic logic either. There basically are 2 options for countries, they either make official rules that remove or dramatically reduce the ability for reclaiming lost profits, or their do an informal strategy where they brick the administrative procedures where these claims end up in "bureaucratic purgatory".
