You should talk to better physicists because that isn’t true.
Have you surveyed a large percentage of all high school physics teachers, or are you just projecting your extremely limited personal experience onto the rest of the world’s physics teachers?
High school teachers by definition are teachers, not scientists. The textbooks used in high schools use simplifications to introduce concepts to developing minds. There is no way a school teaching teenagers would get into the complexity of theories governing our reality.
What people fail to unterstand, physics teachers included perhaps, is that physics doesn’t describe reality, but models of reality.
As a physics teacher (not kidding here), if you want to be taught straight out the electron wave functions in 3 dimensions in high school you might consider not doing undergraduate physics. And I don’t think I’d bother being a physics teacher when more than 90% of my class don’t understand what I’m talking about.
My high school physics teacher would always preface by explaining how the lessons and experiments are only valid in a vacuum.
