HaLeiVi: I expected better from you. I thought about explicitly stating it in my last post but I was hoping people knew it on their own. The Mitzvah to eat Matzos has nothing to do with the story of Yetziyas Mitzrayim. The Issur Chametz has nothing to do with any historical fact about leaving Egypt. (And, unless you assume it was Leil Haseder, the reason they had Matzos was because bread was Assur, not because the Matzah itself was a Mitzvah.) This is clear in the Pesukim as the Mitzvos of Chametz and Matzah were given before they had to flee Egypt.
Also, the Achronim (there’s a T’shuvah in the 21st or 22nd Chelek of the Tzitz Eliezer that quotes these) bring down a few Mitzvos that require a special Kavanah because they Torah requires something more than just doing them, including Tzitzis (Urisem Uzchartem) and Sukkah (L’ma’an Yeid’u Doroseichem). Matzah does not have an additional level of Kavanah necessary for remembering the bread when we left Egypt. That part of Matzah, the Vayofu Es Habatzek, is part of the Mitzvah of Sippur Yetzias Mitzrayim at the Seder, not part of the Mitzvah of Matzah.
