I have been thinking about the mail from the nickname Satoshi Nakamoto, whoerever it is. His argument is not about the technical side of the debate but about politics and long term future.
I think people need to talk less about the technical implications and more about the political implications of this fork.
The argument of this guy is that if the XT fork is sucessful, that means that in the future someone with enough political influence can make a fork successful. That means that one days the President of the United States, who definitely has enough political influence, will be able to push a succesful fork. And we all know what that would mean: no more 21 million limit. We will be back to central banking.
The argument that the community will decide what is its best interest is invalid. Aristotle already knew that democracy turn into demagogy. And history and economics show that the outcomes of democratic process don't align with the best interest of the voters.
Basically the problem is that: by forking we are choosing a democratic political process, and it's the very same process which lead to central banking and is currently unable to stop it.
Just because someone makes a client (XT or original satoshi client) doesn't mean they make people choose to use that client.
If that were so then Satoshi himself had political influence thus negating your point entirely.
I don't see anything that XT is doing other than allowing people a choice to switch their client to one that supports bigger blocks (and a few other minor things).
Ultimately people choose what they want to use.
Political influence lol.
Sorry but I make my own choices by thinking with my brain, not who is in the lime light.
