BMI is a somewhat valid indicator of health for most members of society, which makes it a reasonable population health metric.
That’s a half truth to some extent. Muscle mass isn’t the only thing that fumbles the BMI math. The calculation is also notoriously less useful for women in general, and for black/latino women specifically even more misrepresentative. And even outside those groups BMI isn’t really a “reasonable” health metric by today’s standards. But it ins’t totally useless either, so I guess it depends on what we mean with “reasonable”.

and its also not properly weighted for height. at 6’5", I can be unhealthily thin and shown as 'nearly overweight"
