Isn't It Odd?

I was watching the news coverage of the rioting going on in London ahead of the G20 meetings, and one thing struck me as being exceedingly strange: The crowd of anarchists, who are chanting slogans like "abolish money," seem to have a lot of very nice cameras, which they are holding over their heads to take pictures of the scene in front of them. I wonder what they would use to buy cameras (and other things) if they abolished money?
