Earlier quoted context omitted.
It's a remote incendiary device. That anyone can just buy and use to burn down any structure with no barrier to entry. That's the point. Why are people so obtuse?
If you want to burn down a structure then a molotov cocktail is a lower barrier to entry and requires less access than this candle would. And if you have the access necessary the a remote control kids toy plus some fuel would be almost as easy. At best this gives some plausible deniability. If a lot of people really wanted to start fires I think we'd see more fires.
If I was going to burn down something it's not really great.
