Well, it's not quite as simple as that. We're talking about a stochastic process here, and while a "hand-wavy" proof may satisfy some, there's a Little ;) more to it: http://www.ece.virginia.edu/~mv/edu/715/lectures/littles-law...

Fair enough, although even that terse lecture hand-waved (by leaving it to a reference) about ergodic systems.

I think the deeper point is along the lines of Wigner's classic "The Unreasonable Effectiveness of Mathematics in the Natural Sciences"

It happens to be the case that elementary dimensional analysis is sufficient in the case in hand -- and it often is.
