Maxi it does not work like that once fans go they go for good. The fanbase is made up of many complexities fathers taking sons brothers going mates etc.
You can't build that once its gone.
I doubt very much that that will happen. Supposing you and 500 others stop going from next season. You will easily be replaced by people happy to pay £x for their ticket. They won't know any different as they won't have been effected by 20 years of price rises. They will take their sons. Their sons will pay whatever is required for a ticket. The cycle will continue like it always has done....
