Aside from the legalities, with COVID-19 already circulating in the neighboring states, would the practical benefit of closing California’s borders, to stop a few people still traveling for non-essential reasons, outweigh the costs? Enforcing a closure at the land borders would tie up numerous law enforcement or National Guard personnel, who could be performing other important duties, such as enforcing health regulations and maintaining public order. If the closure weren’t total—and given the interstate supply chains for food and medical supplies, I doubt one could remain so for long—it would also create highway congestion, impeding the movement of these and other essential goods. There are only so many trucks and drivers, and they need to be kept moving, not held up in long lines at checkpoints.
