That's a kind of meaningless comparison. Peanuts are about 8kJ per gram supposedly, by your measure we should ban even small amounts of peanuts on planes because 100 grams of them contain more energy than a hand grenade. Without talking about the time frame over which the energy can be released you'd have to make sure that everybody went onto the plane completely naked lest their clothes ignited.
Not good enough, body fat contains about 35kJ per gram. So nobody with over 1lb of excess body should be allowed on board. People are known to occasionally spontaneously combust.
