You don't understand how Lightning protocol works to claim it's centralized. It's way less centralized than solutions proposed by XT or Classic, which lead to node centralization, this is why they have fallen by its own weight and no one cares about them anymore, because at the end of the day Core devs are the better devs.
Bitcoin will scale to mass volume payments, give it time, the smartest minds are working on it as we speak.
In the meantime, no one is having serious problems using it and it is in any case a better gold already.
