The writing is okay, but the main premise is problematic. If a civilization needs to use such means to expand its territory, the countdown to collapse can already begin. Everyone can obtain a large amount of land and resources at no cost, and cities and various settlements will disappear rapidly. Except for high-level positions in government departments, all other social industry positions need to be replaced by machines: whoever can be a lord will go to work as a cow and horse! As people disperse, people's communication will rely more on the Internet, offline communication will gradually disappear, physiological needs will be replaced by highly anthropomorphic robots or biochemical people and other similar things, and the fertility rate will drop sharply! Even if the government implements policies such as artificial care for the population and centralized nurturing of cubs, it will inevitably lead to the collapse of the family system. (I can be a lord myself, so why should I marry you and have children? I can't be cool myself?). Population decreases, society disintegrates, and civilization dies!

It's basically a running account,
