Digitalis has hundreds. Of Fifties. And many more.
I certainly understand folks wanting minimal kits. That's necessary for mobility. Schlepping tons of stuff ain't fun when it happens too often. Accumulating stuff is for those with fairly permanent homes. Oh, all the media I've left behind in various moves...
I *do* have minimal travel kits. But like any, those kits tend to expand. Yes, I can get by with a few. But they aren't sufficient.
A parallel: I really don't need more than one guitar, eh? But I somehow find myself with the Ovation 12-string, Ibanez 6-string, Martin Backpacker, Dobro-type resophonic, Aria jazz electric, Tamara electric bass, other guitars (and maybe a handmade classical upcoming), the banjos and lutes and dulcimers and mandolins, etc. Of those, the Backpacker and a banjo-ukelele are the "travel kit". But they aren't sufficient.
