I haven't heard of someone freeing themselves of a comfortable living, or freeing themselves of a nice place to live, or freeing themselves of a loving relationship.

Well...sure. But presumably, people don't make a conscious choice not to take on those things, either. And that's what the word 'childfree' was created to connote: someone who's made a conscious choice not to take on raising children as a part of their life. The point of that coining was to make a deliberate contrast with the term 'childless', which carries with it connotations that don't apply to *anyone* who's made a deliberate choice not to have children.

I guess I'm not sure what your objection is to making a "value judgment" about your own choices.
