It isn't the only way out. Let the clubs fail. They'll all start again. And owned and run by fans this time.
Start again - just like Darlington did? A lot of clubs will sink like stones if they go bust. The ground will go, the training facility will go, and local interest will go with it.
Some clubs may come back, but it'll take 15 years and a lot of dedicated fans just to get back to the football league again. Having a few thousand people anteing up a few hundred quid doesn't get you very far.
