Bitcoin added 66GB to it’s permanent ledger in the last year. Saturated 16Mb blocks would add a Tb a year. It’s hard to see how that won’t be centralizing after a few years and people need 3TB just to get started. Not to mention the task of syncing and transferring on a less than perfect connection. Yes, storage does get cheaper, but cryptocurrency is outpacing it dramatically.

And even with these big blocks, we’d have nowhere near a competitive solution, less than 7% of Visa volume. “Raise the block size again” would only get so far. We need something better. I’m not sure lightning is the answer, but at least it shows such a thing is possible. We don’t need big blocks.
