To repost my original point in the post that was taken down (thanks, mod!):
Torah: Just like you wouldn’t want a doctor without a degree, no matter how knowledgeable, you would probably prefer a rabbi with semicha over a random rebbetzin. Even if logically, for your purpose, either one would do the same thing, we lean towards the one that is accredited. As you mentioned, a title commands respect.
Also, do you know me, or are you just guessing? (If I’m the only wannabe doctor in the whole frum universe, then that’s a shame, IMHO.)
