It's not that BMI is useless, it's that it was intended for population-level body data, not individual health data. It's not totally nuts to use it as a starting point to determine whether a person should be concerned about their weight, but it should only be starting point and it's over-relied upon a lot of the time. Moreover, the strength of the association of health with BMI is murky and a matter of some debate. That and the way BMI is used as a blunt instrument for institutional fat hate make it pretty hazardous as a health marker.
