Great insight, except I think you've forgotten "easier to test, modify,
refactor".  As user-stories change all the time, we need to be able
to change our programs -- that is were the simplicity & matter most,
actually -- and test to ensure our changes don't break things.

Except that they often promote ease of testing, modification and
refactoring.  That is what gives them value.
