Why do you think that the accurate size isn't worth representing?
It's mathematically impossible. Political mathematics always ends well
Political mathematics like the Mercator projection which shrunk Africa to an unrealistic degree?
Is that why we adopted the Mercator projection? No, it's not
Obviously. Every projection will be off. Unless you are a 15th-century sailor, there is no reason to favor the Mercator projection over any other one. Sticking with it is also a political choice.
