#art, football and free source?

Last night some footie supporters seem to have pinned something I couldn’t, in a very few words and communicable way:
“£64 a ticket, but without fans, football is not worth a penny”.

Could this not be:
“£X an art? without audiences, art does not worth a penny.”
or
“£x for a social-network/search-engine’s etc. shares? Without users, social-network/search-engine is worthless.”
or

“£X for “authorship”/”intellectual”-rights? Without being inspired by others’ freely provided authorship/intellectual endeavours, yours will be worthless.”

This last line shows off my own in-communication tendencies, however, hopefully the idea gets through..
