No:  The op-ed piece's fundamental underpinning seems to be based on the supposition that government simply won't allow it.  While I can see the logic behind that, it is a far from settled issue.  We'll see regulation, yes, but outright quashing?  I doubt it, except for a handful of places like China, Russia, where you'd kind of expect it in the first place.
