It's a nice thought, but it's not realistic. There are bad teams / bad clubs in just about any league you could imagine. Envisioning one where all teams were great, competition from the top to the bottom was great, and nobody had to worry about an exceptionally good team or an exceptionally bad team, is science fiction. It doesn't exist anywhere, not ECNL, GA, or any other soccer organization in the country.
One of the ways some leagues (both professional and youth) deal with this, is promotion/relegation; booting the bottom teams to a lower level, and bringing the top teams up - once per year. It certainly provides reasonable incentive for the clubs in the pro leagues overseas, and it has its advantages in some of the youth leagues where it has been implemented here. But there are an obvious long list of downsides to this approach as well; it's been tried and failed here quite a bit as well.
I wouldn't agree that there are no repercussions for not delivering quality either, although it might be at a slower pace than some would want. If a team blows, and the club blows, it's going to have a hard time recruiting and retaining as time goes on, and eventually it would be expected to be bad enough that the club either bows out or merges/reorganizes with another. It's not the national organization telling them "you're out", it's a natural business consequence of not serving their paying customers over time.
