>What if you do not want to trust anyone?

>Nope. Sorry. No easy to use options for you out there.

Sure but to an extent that's true about almost everything in modern society. If you don't want to have to trust those supplying you with food or water, there's really no easy options to completely supply yourself with either of those. And even with all the oversight and regulation there's still often good reasons not to fully trust (we all know about Flint at this point even if it was a bit overblown by the media)

It's hard to imagine a situation where someone would supply you with something without you needing to trust them on some level.
