So what you are suggesting is that all human interaction needs to be regulated in order to mitigate risk? Would that be a fair assessment? If so, who makes the regulations? Other humans? Do you see the problem here?
This narrative reminds me of the 1993 film Demolition Man. In the film a 20th century cop finds himself in a world just such as this, where all human interactions are controlled, and digressions punished through fines. The plot reveals a society that has eliminated war, murder, crime, disease, and social faux pas. Sounds idyllic doesn't it, expect its not. All the perceived order & discipline comes at the cost of removing emotion from the society as well as creating and underclass of people who simply drop / are forced out of mainstream society. And sooner a later the combination of repressed emotions and repressed people find a common cause.
The point is that we are humans, we are animals, we are not robots that you just punch some code / rules / regulations into and sit back & pat ourselves on the back for a job well done. Societies cannot be modelled by the few without longer term consequences. And most importantly of all, modelling societies to mitigate for risks in the natural world will simply not work. Along with viruses there are bacteria, there are organisms with teeth, stingers, spines, toxins that are a threat to us. Even the air we breath is shockingly thin in context of the planet's size, and easily altered by natural processes. Technically even oxygen is bad for us in so much that it limits the live spans of the cells we are formed of. All of this is before you consider we are flying in an orbit of a giant nuclear reactor at 67,000mph onboard a huge ball of molten rock with a thin crust, which itself is in a planetary system orbiting a galactic plane at 448,000mph, a galaxy which is also moving through our universe at 1,300,000mph. Best of all the universe is filled with various forms of energy / radiation any of which could wipe could reduce us to out atomic components in a matter of nanoseconds without any warning.
And despite 15 billion years of our universe's existence, we get less than a 100 of those years to live our fragile little lives. So here's the cut, we will not accept a handful of people telling us how to live every facet of life, its way too short for that. What you should be asking society is to find ways to help those that might be at more risk without wreaking everyone else's lives. There are many ways these can be achieved through science and medicine, we just need the knowledge, the will, and the focus of those in charge. We need solutions that actually work, not political posturing and regulated oppression. And if those in charge will not, then the rest should remove them & replace them with people that will.
