And this will most likely happen in the context of countries, not ISPs.

Some country will decide to use the entire v4 address space.  If you
want to provide service to that country's population you get an
allocation from "that country's" IP space.  If for some reason that
country decides they don't like you anymore, they simply black hole your
allocated address space.  In fact, all foreigners could be placed in a
block where it can be "black-holed" very easily.
