It's too late to do anything about it for Bitcoin - we've gotta live with the distribution we got. And maybe it won't be a problem. But for future cryptocurrencies, it's something we need to consider. And we need to watch out and be ready to refine the idea if it looks like the new boss is going to be the same as the old boss.
Memcoin in specific proposed something like adding democratic processes into the coin itself. I think that would be the best way to improve the protocol. The next coin should probably include democracy and voting within the coin itself so that holders can somehow vote as a group.
Problem with such a scheme is how to weigh the votes. By held BTC? By hashpower? None of the solutions are exactly
ideal.
It's an interesting proposal, though. Reminds me of "BIP" 2112's proposal to generalize the current "Version"/"P2SH coinbase" mechanisms by embedding the block validation code in the blockchain itself, and letting miners indicate which such algorithms they're willing to endorse.
