There are many who indulge in such fantasies, but I would instead give a warning. The reason you have such fantasies is likely because you, yourself, are competent in the necessary skills. But from there it is only a hair-thin line that separates you from having feelings of actively wanting such a catastrophy to occur, because it would make you and your skills valuable. Beware of such self-indulgence.

It is self-indulgence, because we can see similar fantasies in people with other skills; people collecting guns often secretly long for a collapse of law and order, people who live in the countryside and have horses imagine themselves to be cowboys in a car-less world. People who like to tinker with old cars imagine Mad Max scenarios. Et cetera. None of these scenarios are especially likely to occur; they only persist in people’s imaginations because many secretly hope for them to come to pass.
