I think people miss that there is a very large qualitative difference between "no law" and "law". Even a very carefully targeted law will still have the effect, on the margin, of preventing or stopping compliant activities. But in the case of something like privacy, or control of data about you, maybe that's worth it in order to stop the noncompliant activities.
On a non-hypothetical topic: does anyone have a good resource on the requirements with regard to backups? That's one of the larger technical sticking points for me - do we have to delete from our backups as well on such a request?
