I presume Guy Kewney has earned a comfortable living from copyright.
Now he says everyone else must give up the same right, in exchange for the fame lottery. Lucky duckies!
It's nonsense to say that copyright is unenforceable. YouTube is being depleted every day as copyright material disappears.
The problem is copyright enforcement is that the little guy gets screwed - the cost of enforcement favors large corporations, who can hire the lawyers to file the takedown notices.
