If so, then we do have a fundamental difference of opinion, but I've = misunderstood how you think about trust/centralization/convenience tradeoff= s in the past.

I believe people in the Bitcoin ecosystem will choose different tr= adeoffs, and I believe that is OK-- people should be free to make those tra= deoffs.

And given that the majority of people in the ecosystem were deciding that= using a centralized service or an SPV-level-security wallet was better eve= n two or three years ago when blocks were tiny (I'd have to go back and= dig up number-of-full-nodes and number-of-active-wallets at the big web-wa= llet providers, but I bet there were an order of magnitude more people usin= g centralized services than running full nodes even back then), I firmly be= lieve that block size has very little to do with the decision to run a full= node or not.
