The obvious answer here is probably that shutting down large chunks of the economy like that directly impacts its efficiency and ability to supply people with stuff, and there's probably no way of fully preventing that impact. There were a bunch of rapid demand shifts to different, non-shut-down sectors like home improvement and DIY followed by a huge spike in demand as people caught up on spending, there's not the capacity to satisfy any of that, and it makes no sense for anyone to build that capacity because by the time it was ready the demand likely wouldn't be there any more. (Look at all the big tech businesses that employed a bunch of people and then discovered the lockdown boom in demand didn't last, for example - and it's a lot more easier for them to scale up than a semiconductor fab or a car manufacturer or airlines or fossil fuel production or the entire wood harvesting and processing chain.)
