I don't know if these considerations are that widely shared. Personally I think of three lines of attack: 1. I own my data and should be able to sell my data. For all kind of reasons.

It should be possible to define laws that forbid to copy. I'm fine with sharing my data at a particular moment for a particular purpose. If that party would be forbidden to copy that data I have a chance that I actually can "have the right to be forgotten". Every time a person requires that data it would need to do another request.
