Prepare for the more likely series of events/dangers before the most unlikely. And plenty of people have them and do to prepare for fire likewise with smoke detectors which are pretty much standard in any modern countries housing. Same with the fire services in them constantly reminding people to check them and keep them up to date and not to overload sockets etc.
I would propose the fitness benefit for martial arts and combat sports to push it up there on the list and the potential going professional in a combat sport can lift people out of poverty etc to put it high as a needed skill to some people. And then you have underlying fears and it boosting confidence etc.
Welcome to realistic prepping my friend.
(i would argue and say this falls outside the scope of martial arts as a thing though)
