woodfires are usually restricted in many area, so is scavaging for wood. A woodfire needs more carefull handeling, to prevent forest fire's. Many people don't clean up there firewood coals and ashes properly.
Also woodfires have less accurate control and keeping a little fire going with damp wood can be a pain.

I occasionally use open woodfires to cook, but only on special places, where it's legal and safe. A billycan is good enough for that purpose. Don't even have to carry a stove than.
