So...why do you need publicly routable IP addresses if they aren't

Because the RIRs aren't in the business of handing out publicly routable =

RIPE are really good about making the distinction and using the latter ph=

It's very clear in the ARIN region as well.  From=20
the ARIN Number Resource Policy Manual (NRPM),
<https://www.arin.net/policy/nrpm.html#four11> -

    "4.1. General Principles=20
     4.1.1. Routability
     Provider independent (portable) addresses issued directly from ARIN or=
 other Regional Registries are not guaranteed to be globally routable."

Adding "or globally announced" may stop some of this in the future.
