Why? 

I would like to see some explanation of the multi-faceted rationales for this rather statist mandate, rather unprecedented in the technology history of the USA because it allows for absolutely no choice on the part of consumers/users.  The introduction cited political, economic issues, there are also military issues perhaps, and the capability of the technology involved all hint at a series of reasons that are not clear in everything I've read on the topic.  Am I the only one confused on this issue?
