Is it not perhaps the case that ZERO is the most important since in many
cases its the only one that's well defined?

Lets now leave "important" off the slate.. 

If I allow for the specification of a value I need to know, don't I, what
to do when a value is given.

What does a distance=10 mean for some arbitrary element? How do we view
order or direction?

ZERO.. Zero is a wonderfull number..  x * 0 = 0... but x/0 is undefined..
0 distance is no distance.. 0 time is no time.. 0 is without dimension..

Using distance=0 as the only case for a metric.. is.. well..
