It doesn't seem remotely possible to enforce measures like these--even in an authoritarian state with martial law, strict curfews, etc., the ratio of police to population is way too low to enable such microscopic control of individual behavior. Some percentage of people are going to do as they wish without regard to law or the interests of anyone else. Not even in brutal military occupations can anything approaching this level of control be achieved, and even if it were possible, the totalitarian infrastructure required would have far worse consequences than a disease. The best bet seems to be unified messaging and economic safety net programs that allow everyone who might be willing to comply under the right circumstances to do so. The US response has been a spectacular failure in both of these areas.
