After the trade embargo, the mormans will run out of furniture. They'll have no tables to eat from, no chairs to sit on, no beds to sleep on. After a month the mormans will be exhausted and starving and ready to topple over with a single flick.
You haven't seen the deep stores of folding tables and chairs that they have in the cultural halls (aka gymnasiums) at their local wards and stake centers. They have ten high-quality steel folding chairs for every member that shows up each week.
