No, you mean that's what you'd like to put in that prefix. The number,
by itself, can't achieve anything. What we're lacking is any way to make
a globally-scoped non-routable address. That is, what gives us global
scoping in 2000::/3 (and most other unallocated spaces, one presumes) is
the routability - the two go hand in hand. The routing tables define
the one unique user of a globally scoped address.
Take away the routing tables, and there's no longer any universal
motivation to maintain uniqueness, and that is what defines the
scope of the addresses - they end up being locally scoped within
whatever (vague) domain they happen to be unique within.
