It he were to move block after block after block after block it would crush the price.
None of that has anything to do with (dis)trusting satoshi's judgement. He can crush the price, but didn't do it. Even if he would sell his coins, it would just lead to a better distribution with less coins on one big pile. And even if most users don't like it, (dis)trusting satoshi is not going to make any chance. Besides, the account is banned to prevent it being compromised.
I'd love for satoshi to come back and join discussions here though.
