I agree, early adopters getting rich is not a bad thing at all.
Bitcoin is not intended to be a get-rich-quick scheme, it's designed to be digital, anonymous, and inflation-resistant among other features. It does what it's supposed to well, and those who are just getting into it can't complain because they didn't get free money- that was never the point (just a lucky bonus for some).
Early adopters are a problem to non-investor type bitcoin users. It may lead to sales yielding greater profits, but may also diminish profits. Getting into the game just for speculating is a bit selfish IMO.
