I don't think this is as problematic as you are perceiving.

In the case of spanning regions and scattered across regions, that is the
reason for the "plurality" provision. It allows a company to keep some
portion of its assets in region and still address its out-of-region assets so
long as none of the other regions contain more of the network using ARIN
region numbers than what is in the ARIN region.

As to moving, yes, corporations often use DNS changes to move the
service for "www.support.foocorp.com" from one place to another (or
to balance it across many locations), but that's DNS. Policy here is
about the numbers and corporations rarely move the numbers around
in such a scheme. (Anycast notwithstanding, but I would treat any cast
as used in region so long as at least one site advertising the any cast
prefix was in region).

Mobile nodes that cross RIR boundaries actually tend to get new numbers
when they do so. (At least I haven't roamed across an RIR boundary without
being assigned a new IP address when I did so, and I've been across a lot
of RIR boundaries.

Which would fail the plurality test.

Which would pass the plurality test.

In reality, I think that particular boundary condition is an unlikely corner case.
Where is the other 42% of that network, by the way?

As I said above, the numbers do not tend to move as quickly as you claim.
Names tend to be quite dynamic. Numbers tend to be fairly stable. If they
were not, BGP would have a much higher (and unsustainable) level of churn.

No, actually, most of the other RIRs are much stricter about out-of-region
use of address space than ARIN.

These are definitely one aspect of the intended policy, but not exclusively,

That is a second aspect of the proposal.

I don't think this is just about law enforcement, though the proposal authors
are primarily representatives of US and Canadian LE organizations. I do
think that the primary intent of the proposal is to address a growing perceived
issue with registry shopping.

Personally, I'm all for making the process more open to out-of-region usage
as you described, but if you look closely at current ARIN operating practice
and this policy proposal, you will see that the proposal is actually more
liberal about this than current (though not some prior) operating practice.
