Seems perfectly fine to me. Some essential jobs require manual skills but I think those can be organised to avoid most of the physical human contact.
Some can be phase out by more automation.
And we have so many inessential jobs in this economy that shedding them might be beneficial to us all.
Do we really need new snowboard clothes every season?
Really think hard about it; it's pretty easy to take a whole bunch of stuff for granted especially when you work in high-tech areas. I'm extremely fortunate that I can work from home, but what if my fridge breaks down or I just run out of milk and my Internet happens to be down?
Uber drivers are entirely other thing. Maybe driving people should be only allowed if you have a car that has completely separate spaces for the driver and the rider and where spece for the rider can be fully vented and disinfected after each rider, which maybe again should be mandatory.
A lot of people can't do their essential jobs remotely. But very few of them can't do those jobs not in groups and not in contact with other people.
The world before covid looked how it looked not out of necessity, but just because we didn't have to pay attention to some things.
Solitary confinement is a torture not because of the solitary part. It's because of the boredom part. How unpleasent do you think would be solitary confinement for nearly all people if it was done in a library with internet access and netflix account instead of small dark empty cell?
Touch could be also culturally restricted to closest family with ill effects milder than caused by mild infections you get through that, let alone ncov19.
Some human cultures are less touchy some more. All survive.
Chemical responses to anything less than touch are way less documented and I suspect easily replicated with good quality audio-video connection.
Historically, humans lived in small, close-knit family units or small villages. The human mind is optimized to deal with a social group of about 150 people, not a city of thousands.
A lot of our loneliness and similar problems could be largely resolved if we returned to a pattern of small, close-knit communities as our norm and we could improve germ control at the same time.
It's a general human norm that most cultures promote a long-term, monogamous relationship as the standard. Sex is vastly less dangerous if two people are only intimate with each other and neither of them sleeps around.
Reducing casual social contact in no way means we simply can't get our social needs met. It can mean the opposite. It can mean a return to meaningful social bonds instead of casual hookups from grinder.
