Why would the owners of current teams -- many of whom have invested tens of millions of dollars into their clubs -- voluntarily agree to a system that might see their $100m facilities sitting empty as their club is relegated and they're forced to play in Toledo, Ohio or Little Rock, Arkansas for road games?
Promotion and Relegation exist in European football associations because it has always been that way. If you remade the Premiership today, though, I doubt you'd find ANY support among the current members for such a system to continue existing.
I would agree, but if you are looking to really grow the system then you need a way to add beyond 24 teams or so. I'm not saying this is going to happen tomorrow, but if there is enough support to grow the sport and the league, it is certainly a possibility at some point.
