I suppose it depends on how it’s said but variants of “why don’t/didn’t you..X?” I might mean as “This is probably obvious but why dismiss X?”

“Why don’t you just X…” implies that the (skilled) person you are asking is too dumb to have thought of obvious idea X.

A better way to phrase the question is “what happens when X…” or “what problems does doing X cause?” Implies they tried/thought of X already.
