Let us get back to banks , which implies trust in trade and currency.
Tobacco was and still is a currency and is taxed to the hilt.
If the Government can tax a " commodity " it has some " worth " to the people /traders.
Governments rely on ATM amongst others " ratings agencies " whom are crucial in the recent GFC
debacle.
Am almost certain the ratings agencies would give a triple aaa rating to most tobacco houses.
So the " banks " are most likely to " invest " in tobacco?!
So trust in tobacco at least it is a usable commodity. Unlike fiat " money ".
