I don't think it's ridiculous in terms of confining the virus but it would never be done until it was so bad and then it would be too late. I don't know if you've seen it but the air pollutants in China have dropped to almost nothing compared to the normal because everything is shut down.

Something else has become very evident with this virus.. aside from our trade deficit with China, a bigger problem, it causes a gap in the supply chain..even more reason to bring manufacturing back to North America.
