> ad they been really “essential” we would have kept/invented those trades well before we actually did Unless things change over time, as such requiring new facilities.

Barring nomadic jungle tribes with no persistent possessions or home locations in the first place, which societies are you describing? The fact that our ancestors commonly died of tuberculosis doesn't mean they where happy to do so.
