If you want to buy space and auction it off to lessors, more power to you. I don't think there needs to be a moral dimension to it one way or the other. The RIR system was also not good.
Reduce the importance of IPv4 and the stranglehold of big conglomerates is forcibly relaxed (in this context at least).
I don't like that I've ignored IPv6 for so long that now it feels overwhelming to have to try to grasp. That may be true for a lot of networking folks for whom IPv4 is written in their DNA, given the incredibly slow uptake of IPv6.
