Let me trry one more time, and then if you still don't get it, I will give
up. Suppose a boundary is defined as the high water mark along a river bank.
Further suppose the river bank is irregular, which should not be much of a
stretch if you have ever looked at a river bank. The irregularities exist at
many scales, from broad bends measured in miles, to smaller meanders measured
in hundreds of feet, to smaller gouges measured in tens of feet, to rocks
meausured in feet, to pebbles measured in inches, to small pebbles, ... etc.
Clearly if you consider smaller and smaller irregularities, the length of the
river bank increases without bound, as illustrated by the two measurements
given for the OK-TX boundary. Since you think the length is bounded, it
implies that you stop measuring around features below some size threshold. My
question to you is: At what scale do you stop measuring, and why? Please
actually think about the question.
