"""That would be a difficult law to enforce without declaring martial law.""" I seriously doubt that. There are current laws in practice that would have needed martial law declared to be enforced (or even passed) a century of even a few decades ago. And we're talking about "detain anyone for any period" and such laws, so in comparison the general public could care less about an "only run state-sponsored non Open Source software" law.
