Depends on the setting
I dont loose sleep about someone not calling me by a title earned by my education, its a non issue.
Everyone, including physicians, should eschew the title "Dr." when outside of their own professional settings. Everyone, including PhDs and Physicians should feel encouraged to use the title 'Dr.' in their respective professional settings. It is mostly physicians that I see using the title 'Dr.' outside of their professional setting, though occasionally PhDs do as well.
You can never be safe from a government that can keep you completely safe from each other and the world. You must choose.
