You need it for intersection tests.  You cannot store enough data in 32 bits
to perform adequate intersection tests without limiting the geometry.

You seem to misunderstand what precision anything stored in 32 bits can
possibly provide.  From a more conventional perspective, I would suggest to
get a introduction to combinatorics book and read the chapter on the
pigeonhole principle.
