geometry is everything, everything is geometry
I mean seriously.... how can you think about anything without a space to visualise it in? The simplest meaningful space is R2, enter Euclid. When smart people learn Euclidean geometry they feel like they were born knowing it, because it is implicit in soooo many other aspects of our culture and reasoning. That is the only imaginable reason not to teach it, and it is a poor one.
