"A monad is just a monoid in the category of endofunctors."
Maybe it is, maybe it isn't, but none of that is simple. There's that math joke about proof methods, and this would be "proof by intimidation".
When describing a process: "To measure the inverse reactive current in unilateral phase detractors, just use an ordinary turbo encabulator". Why "just"? Are there other methods? For what reason is this the preferred one?
When giving advice: "Why don't you just use a bash script?" This implies your suggestion is simpler or more economical than my proposed approach, therefore better, but you aren't supporting its alleged superiority with arguments I can counter, only implying it.
