The accreditation system is a good idea, in theory anyway.
I think your post is well considered, and agree with most of it. That said, its fair to recognise that Capital Football at some level, would prefer to have the 'best players' in its FTC sides and the national age grade tourno's, much in the same way that Colleges would also prefer this. So in much as they could establish some sort of accreditation, they are interested in the promotion of the game, and player development, but they are not an an out and out neutral party in what the right model is/should be, any more that the academies themselves, and any accreditation should be treated with some sceptiscim.
It would be fair to say that the local academies have clearly improved the level of Capital Football competitions at Senior and junior levels, that's a net good for Capital Football.
But oh yes, the School holiday branded "programs" are the worst of the worst.
