That isn't stupid and Naruto cant be taken seriously the idiot charges in himself many times so him giving such advice or expecting people to act upon is hypocritical . Anyway to use Madara sama(GOAT) as an example is silly he fodderised everybody until plot shiled kicked in.Part 2 Sakura was stupid enough to think that she can make distraction against Madara after seeing his sensory abilities and despite Narutos warning.
Denki's behaviour here which is reminiscent of something Naruto or Kiba would do minus the jutsu.
