Completely wireless networks only require power. The only way to take them down is to take down every node, when every household in the country could be a node that means the only way to take down the network is to start a civil war.
True, but there are still the options to set up strategic frequency jammers, set up rogue nodes transmitting /dev/random to each other at max speed, nodes with routing black holes, randomly sabotage every TCP stream... etc.
Where can that be fixed? The nodes need to have the intelligence to route around potential rogue nodes.
In the UK the spectrum regulator is looking into "white space" use - basically even though this frequency is licensable, if you are using it in an area where no licensee's are, and you're under a certain power, that's fine. Assume that we can disconnect from their geo-location control databases, and burst transmit across many frequencies - jammers become an unrealistic problem.
