If I don't trust one person, I'm supposed to instead trust a tertiary entity to act in my best interests? What motivation could this third party have other than to simply make money? It seems as though the lightning network is being marketed as a solution, but I don't understand how it isn't simply creating an even bigger problem by stripping me of any/all control.
