Why don't Mongols live in our square brick houses? Living in a yurt?

For the convenience of nomadic life, Mongols used to live in yurts. More importantly, the materials for making yurts are easy to get on the grassland, which has little damage to the environment. Now Mongolians basically live in brick houses and modern houses. Those who need nomadism generally live in a special four-wheeled warm car. This nomadic caravan can be towed away by tractor, which is not wet, clean and tidy, and avoids disassembly and assembly back and forth. There are solar power generation systems or wind turbines, satellite TV, liquefied gas and other modern facilities. Of course, some herders like old yurts, but now they have reduced a lot. This is not only for the convenience of disassembly, but also a form to protect the grassland and the environment. More importantly, the national customs that have lasted for many years have even formed a folk culture.
