No, it's more like saying "Cars which can't operate off of freeways
won't work" because there are a lot of places freeways don't go.
Hmmm... Come to think of it, I haven't seen anyone selling a car
which won't operate off of a freeway.

I've got no opposition to issuing addresses based on some geotop. design,
simply because on the off chance it does provide useful aggregation, why
not.  OTOH, I haven't seen anyone propose geotop allocation as a policy
in the ARIN region (hint to those pushing for it).
