The first part is non sensical. The red dots I mentioned are not vaccine related, they are just an illustration as to why, regardless of how good/bad the vaccine is, the numbers in hospital will rise. Sure, the dots are totally random and people may be in hospital for different reasons but you will be able to write exactly the same thing about the dots as you did about the vaccines.
The second part is fully documented. It is not wrong.
The last is a straw man: no one suggested vaccines were the only thing you needed to do/have. I don’t think anyone even suggested we might get rid of Covid: it’s here to stay for the moment. However while it may not be sufficient, having the vaccine certainly is a necessary condition to fight it off on a population level. And keeping it up to date, regardless how many times it is necessary, whether to counter waning immunity or to combat a new variant.
On a personal level it is possible to fight off the virus by staying completely isolated from anyone outside your bubble (this is what NZ did at a population level at the beginning of the pandemic). You can order whatever you need online nowadays, WFH, and if you live in the countryside you may enjoy healthy long walks. But the one thing you cannot do is have anyone from your bubble putting a foot wrong.
