Why would we need that? I think a lot of people will get immunity the natural way, even now a lot of people are having covid w/o any symptoms at all, and they will have immunity.

Not sure this immunity lasts long? So immunizing a herds-worth in a small period (2 weeks? 2 months?) might be a thing.

Why would we need to vaccine absolutely everyone ? isn't herd immunity a thing?

Still, it would be a lot of people: 50 to 83% [1], and more importantly, it has to be evenly distributed. It would be pointless to have developed countries safe while the rest of the world is in chaos. We're a global economy after all.

This is false, immunity is strong and long-lasting. The news is trying to sell papers. A vaccine is also an attenuated version of the virus so if becoming immune from the virus doesn't last long it won't last long from a vaccine.
