If the world had collectively done nothing about COVID over the past two years, sure, the pandemic might be "over" by now, but the total death toll would likely be much higher than what we'll probably end up with when all this is actually over, given our current path.
I'm not thrilled with how the past two years have gone, but it could have been much, much worse. It could also have been much better, if it weren't for people using the virus to score political points.
Even with a mix of vaccines and natural immunity, I don't think we can rely on natural immunity to solve this. That just doesn't pass the smell test.
There is zero excuse to push lockdowns, masks or any of that nonsense at this point to “protect healthcare”. Healthcare should have been “protected” by now if this is supposed to be a normal thing
Gaining herd natural immunity implies a lot more death. Also natural immunity wanes after a while, and variants can work around it.
So no, it's not the only way, nor is it even a certain way at all.
