Agreed, I think the doomsday prepper angle makes it seem absurd. But take a step back and this is an INCREDIBLE display of technical capabilities of a single person. It crosses a handful of domains in terms of designing, building, assembling, configuring a Thing. Plus the background detail on component selection. And the writing is tight too.
I build things that roughly resemble this (low volume, custom, solving use cases that are too niche for an industrial offering to be created), for money. I'd hire this guy in a minute to outsource things to or collaborate with, so I see the project as a kind of personal resume.
IMO he should find a specific scenario where something along these lines would be valuable. One I am personally involved in is marine electronics diagnosis. Primarily NMEA2000 networks and the devices on them, and the same devices on Ethernet. It's too much detail to go into, plus I'm on a flight after spending a week in Vegas for a trade show, but with just a little bit of reconfiguration work this could be a Thing that higher end marine electronics techs would really dig. Then I think you could also delve deeper into the considerations put into the design and component selection details.
