that is kind of cute, but I don't see that it is not strictly isomorphic with a) Euclid's usage, and b) the standard, modern usage

From the abstraction of the unit, one now has a standard of measurement. Having established the unit, quantitative trichotomy is now possible. For example, if any two magnitudes are composed of units (or multiples of units), then it is possible to tell the difference in terms of units. Think of this with relation to the ratio of magnitudes where it is only possible to tell if equal, greater or smaller, BUT NOT by how much greater or smaller. > > > > The stage was now set for the final step.
