If a space elevator happened, I would certainly make sure I don’t live in its flattening path around the equator

We have a free eternal source of energy.
It’s called solar.
If a space elevator became a reality, the real problem would be that it can get destroyed easily by terrorists or even just a defective satellite in low earth orbit crashing into it.
And then you have a 20000 mile long cable crashing down on earth at supersonic speeds.

wouldn’t it be a 125–250 mile cable tops?

No, the other end needs to be in geostationary orbit. Otherwise the wrapping of the cable around the equator will start a lot sooner.

How do you anchor the end in space so that you don’t just retract the cable every time you try to use it?

That’s the neat thing about geostationary orbit. If the station at the upper end has enough mass, its own centrifugal force keeps it anchored in its orbit.

If you figure that out give NASA a call, they’d be real interested.

Oops we accidentally cut earth like a big wheel of cheese
