I'm not sure you're right. In such a situation, when a club needs money to pay their players etc, the only option they'd have is for their owner to pay and write the money off. Not all owners can do that, so clubs (with high debt) would immediately be in trouble.
I imagine the FL are aware of that, but it's not workable to stop clubs giving security on loans etc. If clubs were prevented from running at a huge loss it would help. Foreign owners (including northern monkeys) that have no real interest in a club will just ditch it when it's not giving what...
It's a club membership, with rules. Just like there are rules on how many players you can have in your squad. 'But I can afford to employ 30 players, and they want a job, so who are the FL to tell me I can't employ them all?' Them's the rules. You can employ them all and play football somewhere...
Because the football league can set their own rules. You can pay your £20m (thank, by the way), their rule should be that for FFP calculations, sponsorship deals (and all others for that matter) have to meet certain criteria.
That's not a fact. They'd need to sell the club for what they could, and they'd probably get more if they sold to someone who wanted to keep the club, given that the ground is not worth much as anything but a football stadium.
Cash is obviously important, but it's not the only thing that matters.
Those organisations are not very similar to football clubs. They are generally run for profit, and they don't have many thousands of fans that would suffer if they went out of business.
