Here is the answer for those who want to peak:
I had to look this up myself, cause I wondered if walking was considered "work." They are permitted to walk but only within a limited distance and we do not know the distance. It's about the purse. I don't know if the purse itself is allowed - I've not found anything saying a purse in and of itself is a problem - but it's about money. They aren't supposed to be carrying money, buying things, conducting business, etc. It appears to be based on the assumption that a purse would have certain prohibited items in it, like money. This is, in fact, one of the reasons they aren't allowed to drive - cause they'd have to have the purse/wallet for license, money, buy gas, etc.
That's what I read anyway. Someone can correct that if they find otherwise.
