This amounts to an optical illusion. The ground doesn't "rise" to block your line of sight. It appears to rise, when interpreted in a specific narrow manner. But in reality, there is no object blocking your line of sight.
If I'm standing on the peak of Everest holding laser pointer powerful enough to reach the moon...well you're telling me that would be impossible because something that isn't the tallest point on the flat earth reaches up and interrupts the beam. But I'm already standing on the tallest point. Please explain how I can simultaneously be standing on the tallest point but also have my laser beam broken by something taller. Doesn't make sense.
The ground appears to rise, yes. From the perspective of the person looking into the horizon, the ground will appear to rise to eye level, that is how perspective works. It seems like you grasps this concept, so well done. If you want to call it an optical illusion, that is fine by me, I personally call it perspective though.
Based on this concept, you can understand that the higher you get, the farther can you see over our plain earth. But even on Mount Everest a horizon will form at eye level, and 100% optical.
Yes.
How
Here is a orthographic view from a top that is 1 mile high, how the horizon rises to eye level .
