No, and it's not even possible to completely stop human movement. At the end of the day you need trucks to get across, etc. But getting close to perfect isolation is feasible: this is where monitoring and testing becomes most important, as you have to react quickly to contain any outbreak leakage. Importantly, the key benefit of this approach is that it allows you to open up in a controlled fashion areas that are clear of any outbreaks. So while the measures are most extreme and most costly up front, they ultimately are economically advantageous because they are of shorter duration.
