The long term data will be fascinating. Less travel means fewer car accidents and better air for example. As air quality is a key proxy for longevity/many diseases this alone might add a long term positive. Not to mention all the other infections prevented through social distancing, think flu, measles, ... On the other hand especially the early days (or current reality for the US) meant much stress, especially for parents. Busy hospitals are also a challenge and can cause mistakes - and yet at the same time avoidance of less necessary procedures might in some ways again add a positive angle. My point being it's all about the kind of data and timeframe you look at. In more practical terms the real consideration of the lockdowns needs to be counterfactual: how many people would have died without the lockdown. This by definition is really difficult to do as it's to a large degree guesswork.
