I am with Hal Finney here: Any successful replacement of the Bitcoin block chain will forever undermine the credibility of any successor. How is an investor to know that it won't happen again?
Rebooting now may benefit a few thousand early adopters. What happens when hundreds of millions use Bitcoin 2? They'll be just as jealous and envious of you as you are of others. Given the precedent you want to set, how will you argue against yet another reboot?
There is no point in ETH except making money.
