It's a pretty straightforward geometric argument, from your own analogy

I'm sure there's a coherent rebuttal but "That is plainly rubbish" isn't the reply I'd expect in good-faith discussion

It's well in the realm of obvious, but possibly outside the realm of personal experience on your part.

I think pointing at Greenland for a start and asking you to think about the problem for a bit will lead to the same coherent view on the matter.

		Is this about driving to an island? If you need a plane or boat to the island and still call that trip "walking", then someone can take a plane or boat to the island and rent a car and call it "driving" or "driving plus walking". Or if you're just saying that a very good backpacker that happens to be in greenland can get more places by walking because of a lack of roads, that might be true. But for a normal person in a typical household, their walking range is not that big. If you're in the US or Europe the roads reach almost everywhere.
