If the Tzaar is enough to move you out of your house, you’re Lechatchila allowed to move out of the Sukkah.
But you aren’t really mitztaer. It’s a fraud.
So when he told us about the whole Makifin Debinah and gave us Tzar, he didn’t cause us to lose out on fulfilling the Mitzvah of living in a Sukkah (another Mashal – if I keep you up all night, was I mevatel your Mitzvah of living in a Sukkah?)
It’s more like he set up a hose on the schach to make it rain, or stole your blankets, etc.
Also, if “Makifin Debinah” is a real cause for p’tur, and Hashem didn’t want us to sleep in the sukkah, he wouldn’t have given us that part of the mitzvah. It’s like you guys are reading the Chumash and/or Shulchan Aruch upside down. It’s a perversion of the Torah.
Also, you’re not really mitztaer. It’s a fraud.
