I would imagine you would defend this Owen. But I didn't misunderstand.

ROAs should be signed by organizations who receive IP space from the 
RIR. They are the ones responsible for that IP space. If you let these 
organizations re-assign to other Autonomous Systems you start to void 
the RIR function. This has nothing to do with ISPs assigning IP 
resources to their customers in order they can connect to the Internet 
as it has always been. Of course some will defend ISP to assign 
resources to another ISP which is an ASN as it doesn't need to pass 
through the RIR policies directly.
If an organization who is an Autonomous System get their IP space 
directly from the RIR then it can freely and easily sign whatever ROAs 
they should.
