Earlier quoted context omitted.
I like how you go on and on as if I hadn't written two paragraphs to begin with. I point out the costs of not touching being minimal exactly because I anticipated a tiresome argument whinging about all the other things we won't be able to do anymore.
The costs of avoiding direct eye contact are minimal. The cost of not wearing a crucifix are minimal. There are social benefits to touching, and most people are fine with casual touching. You have failed to demonstrate why touch is a special case. You can refer to my argument as whinging or tiresome if you like, but it that doesn't change its validity.
That's a nice assumption. Are you sure about that? Have you asked most people?
You might find that there are a lot of people who don't actually like it, but who find the consequences of making a fuss about it even worse.
