Many of the rules say "unless authorized by the administrator, no person
may..." and an instruction from ATC =is= such an authorization. So it's
within the rules.


Negative. "Administrator" means the Federal Aviation Administrator or any
person to whom he has delegated his authority in the matter concerned. If
"Administrator" included "ATC" then there wouldn't be any need to
differentiate between them and we'd have no rules that included "Unless
otherwise authorized or required by ATC".
