You fundamentally misunderstand the situation, then.

ROAs must be delegated according to the way networks are delegated. Lots of ISPs get addresses from upstream ISPs who get them from upstream ISPs who get them from ARIN.

In the case where IP addresses are delegated ARIN->ISP A->ISP B->ISP C, for RPKI to function, it has to be possible for ISP B to get a ROA from ISP A and for ISP C to
Get a ROA from ISP B.

ROAs have to be representative of the ORIGINATOR of the route in BGP or they are useless.

If they have allocated a block to a customer they should be the ones responsible for creating any ROAs they need for that IP space (in fact ideally they should create for the whole IP space anyway).
