Living as a full-time nomad does not mean trading in a life of domestic stability in exchange for a life of continuous travel. However, it doesn't mean that a domestic existence is completely off the table, because you can choose to have a flexible type of nomadic existence where you utilize several different countries as bases of operations, for example, simply changing every few months so that you never grow tired of a single place, and instead can benefit from the best aspects of each destination depending on what time of the year it is.
For example, a full-time expat might choose to have a winter home in Cancun so that they can spend December through March on the beach, and then have another home in the countryside of Italy for the spring and early summer months, and then another house in the mountains of Colombia for the late summer months when it is exceptionally hot, thereby allowing you to keep yourself in a continual state of perpetually perfect weather because you are simply changing locations before it gets too hot or too cold. This is the flexibility that the nomadic existence provides.
