There are a small number of examples, of intellectual property that exists solely by convention and yet has value.  But you're correct: the property structure of IP addresses is ambiguous.  We never had to define it because we had free supply, but times are changing.

If I recall correctly, the ARIN RSA only applies to resources acquired from ARIN.  It's a contract for ARIN services and doesn't cover legacy blocks, blocks from other RIRs, etc - it doesn't automatically extend ARIN's authority.

I agree.  Which is why ARIN should keep their Whois updated with accurate data, rather than fighting for control of resources beyond RSA scope.
