nah, you maybe right technically with the data-center argument, but
not politically. Everyone has the 'right' to proper redundancy for H/A
if they want/need it. Actually, the sooner the IPv4 space gets used
up the better, then everyone will have to migrate to IPvShit, and be
done with it.

What's the best way to solve this problem?
stop trying to bodge it, and get some PI space.
I'd love but, how can I justify to ARIN a large enough address
block that it won't be dropped by BGP administrators?
The only reason we'd need the addresses is to muti-home.
ARIN says you can get a /22 for multihoming if you can justify their
25% / 50% usage as spelled out in their numbering policy.
https://www.arin.net/policy/nrpm.html#four322
If you can't justify that, then get a /24 of PA space from a
provider that *will* allow you to reannounce that /24 via an
additional transit and *will* provide you with an LOA that you can
provide to that additional transit operator.
The number of networks that filter prefixes smaller than /22 don't
appear to be that numerous IMHO, but if they do, your /24 will still
be reachable as they'll see the larger /19 or whatever from your
provider that it's carved out of.
I am under the impression this is not reason enough
for ARIN, that they are in a rationing mood when it comes
to handing out IPv4 address blocks.
As well they should be. IP resources are scarce and people are
wasteful and greedy.
Most offices don't need BGP multihoming, or any sort of inbound
multihoming at all-- just outbound which is easily done without the
assistance of the ISPs themselves or ARIN by using NAT and upstream-
failover features commonly found in most routers.
Most world-accessible servers that are important enough to need
inbound multihoming should be sitting in a datacenter which has
significantly more professionally-managed multihoming than small
offices.
And before the flaming starts, remember that I said "most."
