But thanks to both of you, reading this (though not fully understanding the concepts but getting closer every day), as well as other very thoughtful discussions about CN in other XMR threads is the main reason I'm speculating on XMR.  I (and I hope most others) condemn BCX's childish, terroristic threats - there was a better way to spark this debate than to give an arbitrary deadline - but I am glad it is happening nonetheless.  There are very few XMR transactions now, I hope and expect that to change in the coming months and years, but I'm encouraged to see such foresight.  

I do think that the possibility that states will crack down on anonymity (banning exchange to fiat, criminalizing use, I could go on..) is the greatest threat to XMR's viability.  But it is a remote one
