Ahaha your comment has been edited after I answered :)
Your claim that you would have had more deaths without a lockdown is entirely unsupported by evidence and contrary to the experience of nations that did not lock down (Brazil, Sweden etc) referred time in the article.
That is true. I have no evidence. This however sounds logical to me: if the hospital are overwhelmed, some people will not be able to given a proper follow-up. and would have died. I am thinking about all these people in intensive care units that barely survive in there. Also, we must keep in mind that many services have been closed so that they could be re-organised into COVID units. The patients usually followed there have not received their treatment and I can let you imagine their status now (not necessarily death, just worse with potential consequences).
However, the evidence you point does not necessarily apply everywhere, and are actually not really evidence too. At least not yet.
As I said, the boundary conditions matter. What could work in Sweden may not work in France (the healthcare system is different), and it is too early to say it worked.
