It remains legal to provide drugs off-label because physicians sometimes know better than federal regulators
It's horrible that A-Z would illegally market drugs for off-label uses -- I would not disagree for a minute with your reasoning! -- but we retain this "escape hatch" because it is important to patient health
without the off-label "escape hatch," we would not have, for example, the glp-1 class of anti-obesity drugs, or, buproprion for smoking cessation, the most effective drug ever found in its area.
We needed doctors working firsthand with patients, and building "anecdotal" (i.e. case-based) evidence to learn things that really matter on a population level
