But seriously -- I agree with the guy. "Used to" feels like a separate word to me -- as if it's a compound adverb, if you will, modifying "didn't." I don't think of it as being a verb at all.
It suits me perfectly... one woman's pedant is another's champion.
I can see why you might agree with the guy, although your argument would be better put if you described "used to" as an adverbial construct modifying the following verb (temporally), as in "I didn't used to like coffee" (ick, that really hurts to type that). Were it an adverbial compound, it'd modify the following "like", but wouldn't modify the preceding "didn't". In the sentence above, "didn't" is itself a modal verb construct expressing emphasis (or affirmation/negation if you'd rather), viz. the semantic difference between "I like coffee" and "I do like coffee".
However "to use to" is clearly a verb, as you yourself showed when you wrote "I swear I never
used to have this problem". Turn that into the third person singular for a second... were "used to" an adverbial phrase as you maintain, then one would have to write "he swears he never
used to has (or
used to had) this problem", which is clearly a nonsense.
"To use (to do something)" is indeed a defective verb as the dimwit from Pennsylvania maintains. However, that's "defective" in the
grammatical sense, namely a verb that does not (and indeed semantically cannot) have forms in all tenses. These are vanishingly rare, but do exist in several languages. The only other one I can think of is the French verb
gésir, if anyone's interested, but there'll be a few others.

Here's another defective English verb for you - "to ought (to do something)" (not that "ought" even has an infinitive form). It's surprisingly similar in many ways to "to use (to do something)" and equally defective.
