This post just proves my point. None of the things you are saying are actual arguments, its just buzzwords. Explain to me why the current structure is unproductive. Explain why regionalising instead would be more productive. Explain why your change is required in order for more emphasis to be placed on facilities, coaching and development. Explain why regionalising earlier will improve the football league structure, what will be better for supporters of, say, Stirling Albion if they are playing regionally instead of nationally? Explain why it would be more attractive to sponsors. You don't do any of this, you just say it would be so as it is obvious, but it isn't.
As for 'bringing up the national team argument again' - you are the one who has pushed this as the main thrust of your argument for pages and pages. If you want to change your tune now then fair enough but don't act as if its weird that people are refuting something that until recently was the main point of your argument.
