That seems like a very hard line to me. Copyright gives fairly comprehensive control over use, however trying to draw a line somewhere down full-control, attribution or no control seems very hard.

As it is today you can use your full control to allow full use with attribution. Of course the "unfairness" probably comes from the fact that you can't force others to do the same.

In my opinion the best option is to keep copyright at "full control" with a time limit. Probably 10-20 years. However that doesn't solve your desire for only attribution.
