Question:
What benefit would there be to limiting the Daled Minim for any of the seven days of Sukkos which coincide with Shabbos to ones home? As the Gemara is discussing the time period of the beis hamikdash which only had a Mitzvah in the Beis Hamikdash for all seven days?

Why is there a difference in the gezeira between Lulav and Shofar?
What’s the explanation for the incongruity of the gezeira on the Mitzvah of shofar during the time of Beis Hamikdash to the gezeira after the churban?
In Conclusion:
Why is the Mitzvah of Daled Minim not performed on the first day of Sukkos which coincides with Shabbos?
Is it because gezeira to prevent one from carrying on Shabbos
Or
Because of the uncertainty whether the first day of Sukkos is Sukkos or Erev Sukkos
