Given our current system its unlikely you could ever make it asymmetric enough to stop the rich unless it was as bad as needing 1 million dollars to defend against every 1 dollar used to attack. At that point the rich have enough power to influence the government and just get them to make this illegal and everyone who uses it face jail time. Given that the nodes can easily be traced back based on the physical location data they are giving out, it wouldnt be hard for the government to send police to any area with a node and destroy it and jail whosever property its on.
Politician/News Agency/Insurance CEO/Hedge Fund Quant: "Oh that's disgusting. An application that tracks people and physical assets and lets you know where every citizen, rival public servant or object has been or whatever they've done before and they've posted it online for free. Where? Where is this thing?"
Someone eventually: "I don't know, one of those stupid '.network' domains"
Politician/News Agency/Insurance CEO/Hedge Fund Quant: "Ugh! Those stupid '.network' domains! (shakes head convincingly)... But I mean there's so many of them though! Which one? Which one is it on?!"
Having considered how I would attack this it seems trivial for the super rich and mega corps to defend against this and maintain the asymmetry however. They would merely need to buy up enough land that outside cameras could not see all of it or build walls to block the view. Then when traveling outside their land they would just need to travel by vehicle that occluded any view of them, and simultaneously have a few other duplicate vehicles move with people in them who don't have to look identical but close enough that the cameras and system cant differentiate.
Its overly expensive to a normal person, but whats a few hundred thousand or million a year to a Zuckerberg or Bezos to maintain their privacy? I know Zuckerberg already does this to some extent with his house[1]
