I agree with you, however it is connected to the original argument because people have demonstrated they won't wear masks, so you need lockdown instead. If people would wear masks, business could go on.

The cost of lockdown is high, I don't think anyone is disputing that. It's a tradeoff, but we don't really know what's going to be best long term. It's hard to measure without all the data, and who gets to choose the metric for success? Is it economic damage, or social damage, or damage to public health that we're aiming to minimize? I think the answer is that they are all competing goals, and everyone is going to be using a different metric to measure success.
