One factor that does play into that is the two layers of allocations framework IANA to RIR and then RIR allocation to service providers which is large but not as large as you would expect given the 35 trillion.  RIR is still stingy old school on its allocations.  

Please name a single ISP that is unable to get enough /48’s for all their customers from a RIR.

Having to do a little paperwork to justify the size of the allocation being requested is not being stingy.
