Sports camps vs. just playing in the yard?

Does anyone else feel like organized sports camps are getting ridiculous? The $400-600 "elite" youth soccer camp happened and my kid learned the same stuff he learns at regular practice but now I'm $500 poorer.

I've started just setting up cones in the yard and we mess around with drills ourselves. Kid seems just as happy and it costs literally nothing except my time. Am I being cheap or is this reasonable?
