The main (only, really, when it comes down to it) difference between a signed and an unsigned integer is that an unsigned integer is defined never to have a value less than 0. There are very valid reasons to enforce such a restriction,
For example?
Various physical quantities only make sense for non-negative values.
Wait a minute... please name one physical quantity that is a) Always integer b) Never negative c) Not just an enum (i.e., not just a finite set of possible values) I can't think of one, which makes me think that your argument about physical values is irrelevant, as you'd never use an unsigned *integer* for a physical value.
