That is true, but I think John is making a stronger point, which I'll make
here: It's perfectly fine for ARIN policy to be contingent on (applied
differently depending on) how a particular block is (going to be) routed.
So if we think it's the right thing to do, we could require in the NRPM
that all blocks in the global routing system be SWIP'ed.  But we *can't*
enforce such a requirement by saying, for example, that ISPs can't accept a
block until it's SWIP'ed.  We can only issue guidelines on what should be
SWIP'ed and make ARIN services (like allocation of additional blocks)
contingent on whether such a policy is followed.  If an enforced
SWIP-before-routing rule is desired by the ISPs that participate in the
global routing system, then they'll have to do so voluntarily by refusing
to accept the announcement of non-SWIP'ed blocks.
