Working on a desktop means that screen and keyboard must be in a controlled and reasonably private environment, a personal boat is ok, a tent can be ok, a camper can be ok, but not a public place with people normally sit behind you. Also when you need to talk a quiet place is mandatory.
Long story short: WFH is NOT working in a café or on a beach. Similarly nomadic work is not open-space work. Those of open space kind should IMVHO classified as dangerous to the point that outside special case it must be forbidden.
