Well, they aren’t fractal, that’s for sure.

It is true that we could make borders more-closely-map to physical features, and that would increase the length somewhat.

And we can define borders however we want, so that’s up to us.

But ultimately, matter is quantum, not continuous, so if we’re going to link the definition of a border to some function of physical reality, I don’t think that we can make a border arbitrarily long.

I’m pretty sure that French territory doesn’t span all time zones on the globe.
