BBO, I see kum va’asei different to shev v’al taaseh. Maybe I’m wrong there, but it’s only relevant to that one post which I retracted.
And as to tefillin, if people wouldn’t wear tefillin because they don’t have a guf noki or because they can’t be meisiach daas, then not only would I not denigrate them but I would say they are doing what halachah says to do. Sleeping outside a sukkah if one is able to sleep in it is against halachah.
