Yes, you’re right, I don’t believe that fairy tale. I trust in the words of Scripture. If something as remarkable as Mary’s Assumption into Heaven were true, it would have been referenced by those penning the words of Scripture.
I’ll say “Hi” to Jesus’ mom when I see her. She’ll say “Hi” back, I’m pretty sure, and then will introduce me to the other children she begat.
Begat? No wonder we have theological disagreements. Evidently we have biological disagreements! ;-)

There may be a little circularity to your argument. IF Sola Scriptura is the way to go, AND IF immaculate conception/bodily assumption are properly de Fide, then it would follow that God would providentially included something about them explicitly in Scripture.
But, arguendo only, IF the Scriptures do, as we maintain, speak authoritatively about the CHurch's teaching charism, THEN believing in Scripture would lead one also to believe in the magisterium, and so to believe what was declared to be de Fide.
So from our side of the divide we do not think that trusting the teaching charism of the Church which was "sent", that is: apostolic, contradicts trusting in the Scriptures.
