Why No Eruv Is Required on Yom Tov
Sources explain that an eruv is unnecessary on Yom Tov because the Torah permits carrying for food preparation (ochel nefesh), whereas on Shabbat all carrying is Torahically forbidden. The Sages therefore imposed the rabbinic safeguard of an eruv only on Shabbat, not on Yom Tov.
