Hm, this is a tough one. I'm not really in touch with a lot of bitcoiners so I'm not entirely sure this is a major disagreement but it definitely feels like one.
I think in order to scale non-custodial bitcoin to the entire world we will likely need to scale the block-size at some point. I think something conservative that grows along-side the growth of technology (bandwidth/cpu/storage/etc) might make sense.
Otherwise we probably need to be okay with a significant portion of the world using centralized or federation-based custody.
