Why don't we create underground cities?

You need to make it safe enough for people to live. Mines are not at all safe and not even safe for the workers. Which is why there's so many problems with them dying. Making them safe would cost an astronomical amount. Underground military bases are build in very specific places to minimize safety issues. Mines are not.

living underground is not the same as underground railroad

it does when you consider we're not living at the mines.

Safety is much the same.

Ease of entry and exit, psychological reasons.

Houses and towers and such are just artificial caves with the benefits humans want like easy access to the outdoors.

In priniciple a basement is nearly there. But true tunnel-fed underground cities outside of certain secret military installations and bases aren't common because it is expensive. Your architecture has to withstand compression and shear forces from all sides. Moisture and movement make wall integrity tricky. Things like sewage and greywater would have to be pumped vertically. Everything would require a forced air system.

Good example is fallout shelters, they are the studio apartment for future millennials

Living in a dirty ass underground city would remind me too much of The Matrix sequels and I would hate it.
