The question isn't whether lockdowns could work or how to make them work. We know lockdowns can work because China successfully pulled one off at the beginning of this debacle and people there were largely going about their normal lives after about 6 weeks. The question is really do politicians in the US have the balls to actually prosecute a successful lockdown in the Chinese style (no leaving the house more than X times per week and only to perform essential activities, checkpoints, non-voluntary temperature checks, forced quarantines, forced mask usage, arrests for non-compliance, shutdown of every non-essential business, etc). The answer to that is a resounding no.
