I'm guessing the concern isn't necessarily the mats used, but people snuffing out the fires, which definitely needs to continue to be allowed?
What about ensuring that the fires can't be placed such that they block people from moving and then prevent the fire from being destroyed by anyone other than its creator as long as that creator is within range (say, 10m)? Then instead of having to kill the fire, just make it a right-click action to snuff out the fire.
When the creator is no longer within range of his or her fire, let the fire begin to die out. Let the grade and quality of the mats used determine how long the fire lasts once the creator scampers off to somewhere else.
If the creator steps away from his fire and then returns, let it repair itself (as if the creator is actively maintaining his fire) until it reaches maximum "health". If someone destroys the fire while the creator steps away, oh well.. you left your fire unattended and it could have burned the place down!
