Some cosmological theories, at least, require space itself to be quantized. Even if theory allows space to be continuous, the fact of having the Planck limit on measurement makes it so in practice.
The whole area of how QM affects the macro world is interesting and slippery -- as in Schrodinger's Cat.
There's a whole lot of good messy fun to be had figuring out the problems with measuring the motion of a macroscopic mass to angstrom precision, fun for which I don't have time right now :-) but all the answers will come back showing that if you want arbitrary precision, you're screwed. Whereas in a Euclidean plane or 3- space, you can gleefully have any real numbers as coordinates, with no quantum fuzz.
