the reason i ask this, is because in peru and bolivia you can!

i will be travelling down the caretera austral next februari and i will do the crossing from villa o higgins to el chalten... where in el chalten you can NOT witdraw money because of lack of ATMs!
in el chalten i will have to pay a guide, who will guide us around fitz roy (ice cap circuit), and need to be payed in USdollars!
if i withdraw usdollars in coihaique (for example), i don't have to carry a large amount of USD the whole time of my trip down the caretera austral.
so it is not possible like in peru and bolvia?
thx
