Not an expert by any stretch but here are some exemptions that would seem to be valid:

1-if you have allergies or asthma, it’s recommended that you launder more often to reduce allergens

2-if you have any type of injury that would be exacerbated hauling heavy laundry baskets around (RA, spinal issues)

3-if you have any type of GI or incontinence issues that would be psychologically embarrassing to have to launder in public facilities

I’m sure there are more, but any of these issues would seem legit.
