Now what about this as a follow-up brain fart; why doesn´t the RIPE NCC just announce their unallocated space? No adding or removing of ROAs, just announce it without a ROA? It will become ROA "unknown" so it will be accepted, and that will disincentivise the squatters from using the space because it´s no longer effective. If someone buys this space from RIPE, RIPE stop announcing it and the new owner can announce it and create a ROA and go on with their day.
(almost) Everyone's capacity for FIB entries is not unlimited, and unless you are suggesting RIPE de-aggregates to announcing every possible /24 of space (this would be somewhere between mildly and totally insane), a squatter can just announce a more specific to get around it
You would also have to take into account everything reserved as well.

TLDR: 212032 is reserved but in BGP...
More reserved/unallocated ASNs currently announcing things: Seems AS214026 is a quite common occurrence, but I understand it was recently revoke or something like that.
