The question is what material you'd use. Plaster looks cheap. Concrete doesn't age well in the elements. Steel doesn't have that look.

I'm not saying build entirely stone structures; no one has done this for centuries. But you do need a stone mason to do the kind of facade detail work you'd see on, say, the Empire State Building.

Concrete has the virtue of being relatively easy to replace. Therefore, it doesn't matter whether it ages well on the scale of millenial.

Though of note--Roman concrete structures, even unmaintained one, have aged far better than their all-stone counterparts from the same era.

They used a lot different/better concrete than we use now.
