Yes, maybe someone who knows more can chime in. US Club has some heavy hitters at the attached to it from a soccer stand point on its board of directors and Kevin Payne is well known as well.
OTH, SCYSA is a state association with a seat at the USSF, along with all the other state associations. If US club is seen as a threat to the state associations, things could get hairy.
The state associations have a vested interest in growing the game at all levels. If US club prevents some clubs from submitting teams because they "aren't big enough" or some other reason, then I believe that will not be seen in a positive light overall and instead as an organization designed to benefit the "elite"
