The fact is that all these covid patients elderly or not clog up the hospital emergency centres and infect essential health workers who then have to take time off, depleting the services available to non covid patients.
Unless you are trying to argue that we should abolish the health system entirely and let only the healthiest survive, ie if you have cancer or diabetes too bad you are going to die anyway so why spend money on you ?
Your arguments simply don't hold water in any civilised society.
You're ignoring the fact that what you said was completely wrong, and putting absurd words in my mouth, using a blatant strawman argument strategy, which as we all know is used when you can't debate the actual matter properly.
The model I advocate has been tested, it didn't leave anyone being told "Sorry, we're not going to help you, go away and die" and it didn't overwhelm the healthcare system.
Australia has a very capable healthcare system, it's not like Sweden is the only developed country and Australia is some backwater slum. Even in slums though, it makes no sense to force people to avoid making a living for themselves. Obviously densely-populated third world countries will do worse, that's just the reality, but even they can't cope with a population of people who stop being productive, which will harm most people and kill many, for the sake of a relatively small number of elderly people.
Throughout history, people have sacrificed themselves for the greater good, usually willingly but sometimes through conscription etc. In this case we are forcing the majority of people to suffer for the sake of a small number of people. It's utter insanity.
Even in actual pandemics which actually kill a significant number of people including young, healthy people, we haven't seen insane lockdowns like this (unless perhaps in some obscure cases). It doesn't make sense to do such harm to an entire country for the sake of so little. People keep saying "Oh, don't you care about a few old people? Don't they matter?" while they themselves ignore the millions of others suffering as though they don't matter.
To relate it back to the topic, which you haven't even tried to do, the economic impact is clearly being caused by the lockdowns etc, and we will only recover when we get rid of the lockdowns. The lockdowns are not eliminating the virus so they are not a strategy with an endpoint, just an ongoing system of economic destruction. It does indeed seem we are stuck in this paradigm for the time being, and the question we need to ask is when will this change?
