That's exactly what needs to happen. If we can guarantee that the virus is out of the region and ensure it can't come back, it would allow us to go back to normal. We could go see our families and friends again, go to restaurants, and basically resume life as normal. Not being able to leave the region is a very small sacrifice to make to get all that other stuff back. I don't even remember the last time I left the region. It's not exactly a need.Do you really want highway patrol to seal off all entry and exit to your regional area? Will commercial flights be grounded? Now your police force will not only prevent the movement of people at checkpoints, but must still allow goods/cargo to flow freely.
Of course you would still allow cargo and essentials, but that's it. The checkpoints would allow transports through, maybe even check for any info to prove it's not just a random guy that happens to own a rig and that's about it. Medical related travel could be allowed too. (you would need some kind of waver or something, not sure how it could work)
