Finally a trait to make paper being edible make sense.
Should also be a boon to people with internal furnace.
I doubt its fun for people to stick 2by4s in their mouth.

You can just give yourself a morale boost for using a lighter, spray can flamethrower, flamethrower, etc.
If the trait does not entail much bonus, then the cost should reflect that.
You could argue to go all the way and make fire tiles increase morale, but if that is too much work then it would never get added.
Which is totally fine.
