I would go with yes, it was a good idea. Or I should say it was the best idea we had at the moment when combating something we haven't come across since WWI (pandemic). Leaving everything as is and pretending this was just a "flu" is a childish way of adressing an issue. Was it the best solution. Probably not, but we can learn from it an come up with better solutions in the future. It sure beats the alternative, bury our heads in the sand just because we don't wan't our way of life disrupted. And I wouldn't say that the full economy was shut down, that's just false and not true.
