Houses change over time. A house could have been build in 1920 without a toilet or central heating. Then over time it got a fireplace on the second floor, an indoor toilet, indoor bathroom, then central heating with gas, extra insulation, a couple decades later double paned windows, hybrid heating with a heat pump, then full electric heating, underfloor heating, solar panels, home battery.
Houses change a lot over time, it is nice to be adaptable and not need to carve out stone and concrete every time you add a feature to a home.
The most beautiful homes I have been inside in Europe were wooden cabins in Sweden. The exposed wood ceiling beams, the unpainted wooden panels everywhere, the little details. I never had that with stone or brick buildings. Mainly because they got plastered and painted over, you almost never see the raw materials on the inside.
What you call "carving out" concrete or brick is not a big deal. You hire workers that will do it, period.
