Who is there to decide which branch is "not-bitcoin"? Is there a supreme court in charge of interpreting every word  (What "is" is?) of Satoshi's paper, and all the foundation documents? Is the self-consistency of all the "protocols"  future-proof? Who has the authority to appoint the judges of the supreme court? The economic mass Bitcoin attracts could be the very factor that undoes Bitcoin. Powerful interest groups will want to butt in.
