I'm just going to repeat what I've already said. New Zealand is proof that well implemented hard lock-downs work. There are many other countries that prove this also, including: Japan, South Korea, China & Australia.
I cannot prove anything about the long term effects of lock-downs because we won't have that data until next year, but currently there is no evidence (that I'm aware of) of significantly increased suicide rates or a high level of excess deaths in these countries. The burden of proof is on you, because you made these statements as if they are fact.
Also, as I've already said, the economies in countries that have contained the virus are doing the same (or better) than the countries that failed to contain it.
I couldn't be bothered compiling data for you because I don't think you're going to listen.
I will deal with the most obvious problem in the proof you have presented, two of your examples of hard lockdowns were nothing of the sort.
Japan did not use hard lock downs, It did very little other than allow people to make their own decisions. It did not do widespread testing, 0.2% of the population were tested, it did not use surveillance, yet one quarter of Japans population is over 65, and supposedly their strategy should have resulted in 400k deaths it did not, it gave sanctuary to the cruise ships unlike NZ.
Neither did South Korea, The used carefully deployed reverse contract testing and they also have one of the best health care systems in the world with the best quality and quantity of capacity per capita.
the other examples are not so clear cut,
China used localised total lockdowns at the start but dropped them early on. China deployed rapid testing and contact tracing. but they didn't get excited by asymptomatic cases they realized early on that nCoV had already been circulating for some time without anyone even noticing.
Australia and New Zealand are not clear cut either. Because of their geographic isolation they have chosen to completely cut themselves off from the world. Both countries are going to suffer significant economic hardship as a consequence and this will feed through into increased mortality.
Taiwan ROC is another Island, they were on it early, no lockdowns, careful deployment of resources, reasonable rules decent healthcare, practically no deaths. Taiwan is not a member of the WHO which is politics and so was ignored.
That is why I say things are not clear cut, you are damned if you do damned if you don't, people are going to die no matter what you choose but the wise old epidemiologists taught us to be humble and measured. Most of all don't act in haste and regret it. First do no harm.
If hard lockdown worked then the effects would be seen in the gompertz curves for different countries with different responses and the effects would be temporally related to the intervention given it is the same virus everywhere with the same transmission characteritistcs the lag would be the same everywhere. JPM looked at this with their quants and saw nothing. cherry picking examples where the disease appears to have disappeared and ascribing that as due by lockdown is classic fallacy. Post hoc ergo propter hoc.
