"Has seen me in the past" and "has my charts" are not indicative of medical efficacy. There are doctors I have rapport with, absolutely. I still have lunch occasionally with the physician who was my family doctor as a child and still sees my parents.

We truly live in the darkest timeline.
Obviously the ideal would be you have a system that accommodates "my kid has a fever/fell out of a tree and broke their arm" majority of medical issues who could be helped by basically anyone trained in basic medicine while also accommodating people who need a rapport with a highly trained/expensive specialist.
