I mean,
should, sure. Do? Different question, that. So's able, remembers to, so on, so forth
There's also going to be a lot of people who's going through things for the first time for whatever reason (visiting, first time under own finances, etc.), or trying to restock, or whatever. Iirc the logistics of how things play out with hurricanes (days warning, etc.) vs tornados (more localized, less warning, so on) leads rightly or wrongly to different prep profiles. Want to say the difference in geography plays into that; there's basically fucking no basements in florida, ferex, and if there were they'd basically be borderline suicide to shelter in (and questionable to store emergency stuff in) due to flooding issues. Having a storm kit is a good idea, storing it can be a different question.
Though the profile for a hurricane kit differs a bit. More food and water, mostly -- partially due to being further south, partially due to hurricanes tending to level much wider swaths of land. Can take longer for relief to reach you, more or less. If I'm not misremembering it, local news stuff is suggesting a gallon of water per person per day for a solid week or so though that's for more than just drinking.
E: It's also good to remember that florida has a pretty hefty population. Even if a relatively small fraction is lacking one thing or another, them flexing all at once in the face of an incoming storm can cause all sorts of logistics problems. Everyone in a tornado alley state might be able to fit in one grocery store but that don't work in these swamplands.
