Uh, no. The IETF decides what it is, and if they say it's private (like they did with RFC1918), then it is.
If they say it's "reserved", it's not up for grabs (neither for the RIRs not for any private deployment either).
"Not RIR space" does not make it "private", there are at least 3 different states.
Best examples are 1.1.1.1 and 5.5.5.5
1.1.1.1 is APNIC space, which was very officially given to CF and documented as such. inetnum: 1.1.1.0 - 1.1.1.255 netname: APNIC-LABS descr: APNIC and Cloudflare DNS Resolver project descr: Routed globally by AS13335/Cloudflare descr: Research prefix for APNIC Labs 5.5.5.5 is part of Telefonica's allocation inetnum: 5.4.0.0 - 5.7.255.255 netname: DE-MEDIAWAYS-20120425 country: DE org: ORG-TDG4-RIPE ... and anyone using it for their private VPN is squatting on address space not belonging to him (and yes, I think this was a fairly bad decision "back when this space was still free" - even then it was not "up for grabs"). Fairly easy this. If it's not yours, or designated as "free for all", you do not use it. Otherwise the ghosts of the Internet will come and haunt you.
