eli5 if maps are inaccurate because we can’t project spheres on 2d planes. what happens if we actually decide to map the earth “by hand”?

Like let’s say that we start on the cape of goodwill for example and follow the coast.

Represent each 1km with 1mm for example on our map (map size isn’t a problem just for the sake of the argument). Getting the directions of drawing off a compass exactly. And just walk around all the coasts of the world.

What type of map do we end up with in this hypothetical?

Simply put, your method can’t work. In general, the line generated by traversing the coast of any continent wouldn’t form a closed loop on the paper when you returned to your starting point. As a simple example, imagine a three-sided continent that reaches a point at the north pole and two other points on the equator. Two of its coast lines run due-north/south and the third runs due east/west. Drawing those three lines on a flat piece of paper doesn’t make a triangle. Using the north pole is an extreme example but the same issue will occur for all the continents. And think about what would happen if you tried to do Antarctica!
