You are (it seems intentionally) ignoring the point that Mercator's area distortion doesn't dangerously mislead in navigation, quite the contrary. Or, if that isn't true, please name some cases where navigators were messed up because they thought Greenland looked bigger than it was in area.
Unless you use a globe, every projection onto a flat rectangular surface distorts.
Now how does that make more plausible the claim that world map makers are inflating the area of Taiwan on purpose?
