12 megapixels at 300 dpi (a typical high quality print) is only a 10 x 12 print. And if you decide you need to crop to get a better composition, more pixels gives you the option of maintaining an 8 x 10 even after you’ve thrown some of the image away.
A poster sized print at something like 24 x 32 at 300 dpi is 7200 x 9600, or 69 Mp. Of course, a poster print doesn’t usually need 300 dpi, as it’s seldom viewed at reading distance.
