I wouldn’t say OP is advocating for everyone to adopt their path, just for individuals who take that path yo not feel stigmatized.

I see two solutions to the issue presented. Issue one, proximity. I personally don’t hear or see the pressure to be in a relationship from ppl who aren’t. But family and friends who have a vested interest in the person, who also think relationship is the natural state will always worry.

The solution to proximity involves part of solution 2 whivh is marketing. There should be a concept of monoship which society has largely forgotten. We had terms for them but never classified as a group. We would call these ppl “hermits” or “spinsters”. In reality introducing this concept and say your are in a relationship, just one a healthy monoship with yourself
