This simply doesn't fly. First of all, 100$/mo is far too much for a
small office, school etc or for every Winnebago in the USA. Free, or
$10 one-time fee, is more like it.

Secondly, even if we get past that, it's the wrong answer. If I get a
/48 from ISP A, and want to use it in "private" mode to set up VPNs
to business partners who have their public connectivity from ISPs A, B 
and C, this /48 is going to cause various forms of head scratching
for the operations people at all those business partners, and if it 
leaks, at all those ISPs. What is this /48 from ISP A doing on a site
connected to B or C, or to a different part of A? Yes, this can all 
be configured to work, but it will be a much greater source of 
operational confusion than a /48 which by inspection can be seen to
be private (not globally routeable) space.
