Well, there's a large middle ground between "little Jimmy's raspi's 4GB sdcard' and 'VISA's multi-PB datacenter'.
While there is certainly centralization pressure on mining, I do not agree that 8MB blocks make it impossible for everyone except for 'powerful companies' to run a full node, especially a pruned one. An enthusiastic early adoptor or investor holding, say, $100k of the token is more than capable of spending $500/yr to run a colo'd node. Would they prefer to spend $0 and host it at home? Probably. But the expense of a high-end VPS or low-end colo box is not totally prohibitive. We're not talking about more than a few rack units worth of HW.
