Your Catholicism keeps you from seeing the logic of what would have been a quite natural reaction from a young Jewish woman in Israel in the last century BC.
The Bible NOWHERE says that Mary had pledged herself to be a perpetual virgin. That is Catholic Tradition - which is sometimes out and out WRONG.
Your Protestantism keeps you from seeing ....
Ad hominems are a dime a dozen. The fundamental problem is that 'sola scriptura' is not taught in Scripture, and yet you see everything through the lens of 'sola scriptura'.

No it is not, as I explained. If Mary saw in herself Isaiah's virgin -- a big if -- she would not point that out as a contradiction to the plan.

And now to the big if. You just got done constructing an elaborate hypothesis regarding every young Jewish woman dreaming of a virgin birth; regarding Mary immediately recognizing Isaiah's prophecy; regarding her nevertheless uncoherent in the light of the prophecy response, -- and none of that is in the scripture. All there is in the scripture relevant to this is Isaiah's prophecy, the account of the Annunciation and Mary's response. I look at the text and draw conclusions. You build extrascriptural hypotheses, like the rest of Protestant wobbly edifice.
