> It's not just preppers.

Maybe, I mean it's a very cost-effective “i need to eat but not think about it” alternative to something like Soylent (assuming you have the storage space), so there may be a non-prepper market, but...

Pointing to a group for whom being preppers is a religious practice (and maybe even a doctrinal obligation) is not support for the idea that the market for a product isn't just preppers.

The Mormons are a great deal more practical about it than these food kits though. Mostly just encouraging canning/home cooking and keeping a rotating inventory of anything that'll keep a few years.

Prepper food isn't really practical unless you've got 100 people to feed and can genuinely use industrial food in industrial quantities.
