Weirdly individualistic and idealistic take from a communist. Not saying romantic love and parenthood is the only path to a fulfilling life by any means, but this is a very strange way to lay out the opposing case. Paint your house polka dots like Madonna?
If you're not going down the married with kids route, it shouldn't be in pursuit of social isolation and shallow self-destructive hedonism. It should be to pursue passions that truly matter to you, to get deeply connected with people in other ways, etc. Of course, there's plenty of people who are involuntarily excluded from the parental life because of health, cost, or other material reasons, but I think that's a different discussion than choosing not to have kids because it's not the life you want for yourself.
