You don't seem to give Satoshi himself much credit. He surely would have recognized the significance of slipping in the 1MB block size and commented on the commit if he felt like discussing it. I'd say he likely had something deeper in mind. But unlike our friends above, I don't pretend that my mind reading abilities are strong enough to overcome the space-time continuum.
Satoshi didn't seem to consider it a problem for bitcoin to centralize significantly:
Forgot to add the good part about micropayments. While I don't think Bitcoin is practical for smaller micropayments right now, it will eventually be as storage and bandwidth costs continue to fall. If Bitcoin catches on on a big scale, it may already be the case by that time. Another way they can become more practical is if I implement client-only mode and the number of network nodes consolidates into a smaller number of professional server farms. Whatever size micropayments you need will eventually be practical. I think in 5 or 10 years, the bandwidth and storage will seem trivial.
