I still don't get the point of a $250 stadiometer, when you could get a $20 steel ruler and just screw it to the wall. Also, why won't these kids get off my lawn?

I agree, he doesn't seem to fully explain this. Why were the "rulers" constantly losing calibration? How does the stadiometer fix this?

The rest of the article I find to make a rather valid point, though. Things are often "SNAFU" for reasons an outsider has no clue about.

This can breed unwarranted arrogance. It can also breed a mess, when an outsider (e.g. consultant, or executive having read the latest "Mind the Gap" opus) starts changing things without understanding what's really going on.
