Agree on both counts, unfortunately.

Unfortunately because Satoshi's coins are indeed a negative for the ecosystem. People need to trust that:
1) Satoshi won't just dump 'em for diversification (I personally doubt it)
2) Satoshi won't dump 'em for some other reason (ie, he goes insane, finds himself under duress, etc)
3) His keys don't get hacked
4) He doesn't ultimately pass the stash on to others who are less ideologically-motivated and less careful than he seems to be

In short, it seems clear that the ecosystem would be better off without having to worry about the above, even if they're only tiny concerns.
