I definitely support civilian ownership of self-defense robots. But for them to be affordable (or maybe even possible), there needs to be substantial production of non-defense humanoid robots like robot maids to build up the supply chain. Even then humanoid robots have a lot more moving parts so they'll never be as cheap as today's civilian drones.
