There are plenty of things to live for, but that’s not even the point. There is a difference between choosing to be social and having to be social because you will get depressed if you aren’t.
I think this need for social interaction is harmful. We did see this in action during the COVID pandemic. So many people who weren’t able to abide by a short lockdown. Lives were lost due to our pathological need for social interaction.
Imagine how many communicable deceases we could eliminate by simply having a 3 month lockdown every other year.
You don't go far enough, every flu season should be lockdown and social distancing protocol should be followed on pain of death.
So is food. If we switch to IV feeding you can also avoid many harms food and drink brings. We can do a soylent green as a stopgap.
