> my right to do with my work as I see fit
You mean your right to tell other people what they can or cannot do.
Copyright does not give you a right to do any more than you can anyway. It removes the normal rights of everyone else.
Without copyright you are still entirely free to sell copies of 'your' things. It is just that everyone else can too, so the normal functioning of the market will drive down the price so it will not suit you individually.
Copyright is really a privilege. It is something bestowed by the public, for the benefit of everyone.

I suggest that might be a risky or weak strategy. People will create and communicate things anyway -- as they have been evolved to do. You will just be removing yourself from the cultural gene-pool.
