Let's just say that you are right about "playing time" being everything, what about 40 plus player high school and 60 plus player college rosters? Players can improve and experience the sport and the team by training and practicing and challenging starters. There are only so many starting positions and so many lines and so many minutes in games. What may make sense, is for coaches to schedule other tournaments, games and scrimmages for the players the consistently get less minutes and give them the opportunity to compete in games.
That's HS and college....youth is where you need to play because 1) you will get better and give yourself a better chance to see the field in HS and college 2)No matter how much you play/train at the youth level you may not get to play when you get to HS or College . So you'd rather have your kid be on a team and not play at the youth level just for the sake of learning to be a team player and not see the field for for say 8 years? Stupid..get over the playing on a big named club Dad. It's for your son not so you can tell your friends your kid plays on a big named club
