I agree, but I do think it seems to have a limited appeal within urban areas, then tunneling connections between server nodes in other cities over the regular internet. The tunneling between cities is still vulnerable, but when it gets cut off there will still be a way of communicating. The nice thing about this when localized to large urban areas is that the cost per capita shrinks. I'd imagine it wouldn't be too expensive to set up a bunch of routers that weren't online. Quick Google seems to suggest that a router tends to cost around $1-2 per month in electricity, plus an up front cost. Create a Kleinrock ecosystem in a section of a city would not necessarily require a large number of people adopting it, but rather a manageable start up cost plus maintenance, which seems almost reasonable. Of course, if a few people are paying for it, you'll still need people to actually use your wacky science project, which may or may not happen... If you build it, will they come?
