I shan't rise to that bait

OK I will for my interest:

If the need is to arrange for air changes to expel human generated
moisture can the wall acts as a contra flow heat exchanger, with the
living space under slight depression and sealed doors and windows? The
cold air from outside migrating through the wall and picking up heat,
thus also lowering rh, as it permeates through the strawbale and daub.
The humid air then being rejected via a fan.

Sadly that cools te straw on the way in..

Drivel is always going on about aircon with heat exchangers etc..its the
best way..you suck warm sticky air out, pass it through a heat exchanger
to heat cold air on the way in.
