So you're saying 'it is for their own good,' is duplicitous, it's really about the person giving/administering the 'encouragement'.

I don't think I ever said that to my kids, but I said it to myself when I punished them.   I never hit by the way.  But in that case, I really was doing something to teach my children there are consequences to your behavior.   

I could also mean the 'giver' is sincere.  Telling someone to take their medicine to control their psychosis, would be for 'their own good'.   

Hmmm, my reaction would change if "it is for their own good" was a request for volunteering, or was a mandate that had to be imposed.   I do agree with imposing mandated behavior when you behavior is harmful in some way to your community.

All these things take some wisdom.      And wise men and women don't always agree.   

I'm not a libertarian.    We live in community and that means we have to have some common civil standards and shared responsibilities.  IMO
