No thanks. I don't accept any of that as fact at all.
"our government is following the best available scientific advice" - Nope, don't accept that.
"the virus will flow through the population until it is stopped by the immunity of those who have recovered" - No, not that either.
"The aim is to protect vulnerable groups by limiting the spread through delaying and reducing the peak infection rate." - Not even sure about that. It might be the aim, possibly.
In short, none of the above are facts. They are conjectures, disagreed with by many. That you accept them, does not make them facts at all.
I don't know whether you are incapable of independent thought or it's just that having nailed your colours to a particular mast, you feel unable to accept the possibility of you having been wrong. Either way, I am not bothered.
