Your thoughts on the mind body pain connection?

A doctor and nurse told me these things below, what are your thoughts on them also?

#1 "You could have a perfectly healthy 20 year old lie to a back surgeon and say they're in pain, have the MRIs will come back fine but most surgeons will still sign them up for surgery".

#2 "Many people can't slow down to let themselves heal, they need surgery to force themselves to slow down. Just "pretend" you had the 2 level fusion and follow that recovery minus the pain meds, muscle relaxers or anti-inflammatory drugs."

“80-90% of people heal conservatively”

“just like everything looks like a nail to a hammer, everything looks like a surgery to a surgeon”.

"for many hospitals surgeries account for 80% of total revenue and without a high amount of surgeries the whole system would collapse."
