Need is as contentious as deserving. It's also not reallocation of a central fund, it's individuals exercising choice on how they spend their own money. If someone from Glasgow decides to shell out on an Arsenal season ticket instead of spending it on Clyde my opinion on it doesn't matter.
Personally, I wouldn't, it's vastly overpriced and inconvenient, so I won't. I'd still go if I was in London or watch on the telly if it's on.
