Storage is not the most important requirement, bandwidth has always been the primary concern. Real decentralization depends on the number of full nodes. If we are not lowering the barrier to full node operation then we are not improving decentralization.

Hmm I'm not sure I agree here. Yes in places with shitty Internet bandwidth is more of a concern, but I the barrier to entry(device cost) doesn't increase with bandwidth, but it does with storage.
I also don't think most people are turned away by either of these constraints. I think most people don't care or transact enough to bother running a node.
storage has always been the main concern, jeff is just completely wrong here. you have to download the whole chain regardless of pruned or unpruned.
