I don't really agree with the "IPv6 think" concept - but let's put that
aside for now...

The default allocation size from an RIR* to an LIR is a /32.  For an LIR
providing /48 site allocations to their customers, they therefore have
16-bits of address space available to them to address their customers.

So, even in "IPv6 think", homes that typically have one subnet have an
equal number of bits to address their single subnet as an LIR has to
address all of their customers.

It seems illogical to me that we've got an 128-bit address space,
featuring numbers far larger than any human can comprehend, yet the default
allocation to an LIR allows them to address such a feeble number as 65,536
customers - a number far smaller than the number of customers for medium to
large ISPs.

The default LIR allocation should be a several orders of magnitude greater
than the typical customer base  - not a smaller default allocation.

Note you say default, as in beginning point, not maximum.
