Gefen, what I was getting at is that I never heard of this concept applied to a gezeirah, only to a n’vuah.
Your case wouldn’t seem to be a reversal of the gezeirah anyhow; who says the gezeirah was to have a house permanently?
I think you’re also getting “al tiftach peh l’soton” somewhat confused with ayin hora (“YOU” would be al tiftach).
