While I agree with your overall opinion, to be fair this course is not for the individual coach 'per se' but for administrators, staff, etc. The National Youth License is designed to provide club directors of coaching, youth coaches, and soccer administrators with the knowledge to successfully structure soccer environments for children ages 4 - 12.
A Youth module license actually only costs $25 (and three hours) for the coach which is all you minimally need at this age to coach a rec team.
Still I do agree with your point in that many people get paid and it is an expensive sport. At least way more than it should be.
