The whole kit-and-caboodle of the real numbers is not necessary.
I believe that most, if not all, of Euclid can be modeled in the "surd plane"
(see also "surd field")

See Edwin E Moise's "Elementary Geometry from an Advanced Standpoint"

From what I recall, Euclid missed a bunch of stuff such as order properties.

And Pasch's axiom was not noticed until 1882
