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.

Not yet, and it is possible that immunity does not last long enough for herd immunity to ever happen. It's too early to tell.

This is false immunity is strong and long-lasting otherwise they wouldn't be sinking billions into a vaccine which operates the same way that infectious immunity operates.

Herd immunity is a thing, but as I heard one scientist describe it: It's not a question of achieving herd immunity or not, it's a question of how. Mass vaccination also leads to herd immunity, it's achieved by creating immunity in individuals through a vaccine instead of by contracting the virus naturally.
