Cost and ease of maintenance. Isn't it obvious? The only ugly thing is instead of having separated multuple conductors without isolation on the wire, you can have isolated wires, and twisted together, so instead of 50 wires throughout the air, you would have one thicker.

Are you going to to pay for the massive infrastructure change that would require?
If you look around, every new subdivision I see being built is underground, in the multiple states where my family and friends live.
In some areas though, the ground is incredibly rocky, or general conditions promote aboveground for new indrastructure, but that's rare.
Anyone learns to just ignore them. So not unsighly becuse you look past them
