Except.. it's not staying the same size and disappearing bottom first. It's simply going off into a point and disappearing in it's entirely. Unlike the sun which stays the same size all day, disappears bottom first, and doesn't disappear into a point.

You really have to be joking to say that this is like how things disappear over the curve when that is not at all like it. I would use your meme to prove the earth is round by contrasting it to the sun and to ships... and to this plane, which is coming TOWARDS you and so can't be disappearing at it's vanishing point...

But I suspect you'll just ignore it because you seem unable to address observable reality that contradicts your belief system.
