Yes a very large number of peopl don’t change their routine, habit or comforts until significant external stimulus is applied.

If a solution depends first on wishing reality was different, it’s fantasy. At best a reality to realize.

What an awful mischaracterization of my suggestion. I suggest that a person change themselves as a way of influencing the people around them (e.g. stop using facebook if they think facebook has a malign influence on our culture).

If any inconvenience at all is too much inconvenience for a person to live by their principles, I would say that person doesn't have any perceptible principles at all. 'Domesticated animal' might be an apt descriptor for such a person, but it's really unfair to the class of domesticated animals because they don't have the freedom to choose anything but domestication for themselves.
