From your wording you seem to be disagreeing with my “tayna”, yet in the end it doesn’t seem so. Were you perhaps a little unclear in replying to a quote, or did I just get it wrong?
Your tayna was that sleeping in the house doesn’t enhance the mitzvah of sleeping in the sukkah. If I understood username correctly, it somehow enhances the mitzvah of תשבו because he he appreciates the sukkah more when he eats there. So it is more analogous to his misunderstanding of the clapping issue than you gave him credit for.
Nevertheless, it still doesn’t make sense, and isn’t analogous to the clapping issue, which isn’t about being mechallel Shabbos (ch”v) to enhance Shabbos at all.
