The only thing needed is acceptance from the rest of the users in the network.
This is truth. But what about the 99.9999% of humanity that isn't on the network?
Getting more users on the network by countering the bad info and propaganda is part of the mission statement of the foundation. To the fence-sitter who might be persuaded to join the network, having a statement issued by The Bitcoin Foundation sounds more authoritative than pointing to a forum announcement.
The foundation is Bitcoin's face to the world, not a mirror for us to look at ourselves.
The rest of the humanity is free to join the network. They only need to read in the forums to start getting the information to start the trip. And one of the first things they will read, and I hope they would be searching for, will be the anonymity they can achieve working right with their bitcoins. This foundation crashes with anonymity.
I think bitcoin doesn't need someone to talk from itself. Code, users, actions and time talks from itself. One error of a bitcoin user and some coins are lost. One error of the bitcoin fat ass target foundation and we can loose everything.
I find this foundation as dangerous for bitcoin as the fat ass MtGox. With both we loose anonymity and the decentralized spirit of the network.
