Ban heavy metal concerts?

I wonder why I haven't seen anyone proposing a ban on heavy metal concerts. Lets look at the typical arguments:

• People spend a lot of money on them (no subsidies available for this particular music, and in fact heavy taxes all around).
• People get hurt. They get stamped down, kicked and pushed.
• It's a "closed venue" for the handicapped, and very petite individuals can get seriously hurt if they enter the thickest crowd. 
• Property gets damaged and lost. Try watching your money or set of keys in a crowd during a heavy metal concert! You just have to hope they stay in place. Sometimes they don't.
• The lyrics are so nasty! They speak of death, mutilation and other nasty stuff. 
• No-one can really breath that much during a heavy metal concert, not even when they are held outside. The body mostly inhales sweat and air with little oxygen.

But wait a minute, perhaps it's not so bad after all? I mean, no-one believes that the nanny-state can help you during a heavy metal concert. People take care of each other in the black sea of a lot of people sharing very little space, while trying to bang their heads with the music.

Just a thought.
