>23 miles is ~0.001 of the Earth's circumference. How can that cause a visible difference in tower height? It seems fairly intuitive that a tiny amount of an insane amount can still be a lot no? I don't want to get too deep in the math right now since it's morning where i live nor am I good at it.... but if we'd just assume the earth was a nice sphere and a quick google was correct about a 12742 diameter then every degree down from the northpole to the equater would be on average a 70.79km difference in "height". Take a thousand of that and you're still dealing with an easily perceptible >7 meter difference. Now all of this is shoddy quick thinking since the earth is not a nice sphere, this heigh difference is better not measured perpendicular to the equator but to the ground or center of the earth, etc but you get the idea i hope.
