In case it wasn't clear, I'm with Garret on this one.  Your intuition
seems wrong to me.  I really don't see how it could be true that
everything I "need to know" about a particular integer or a particular
date in human history can be be expressed in a small number of bits.
The bits serve to point to a particular item in the value space, just
because of a common convention.  Maybe we've internalized that
convention and become very used to it, but it's still just a convention.
The idea that it takes 8 bits to represent the numbers 0..255 is based
on assigned conventional meaning to those bits.  We could establish a
similar convention for other kinds of values (such as US Presidents), or
location on earth, or etc.
