I am a wife of 22 yrs. and mother of 4, (ages 20-10). My husband and I started together on his first yr. in college. Between schooling (now PhD. Medical Physics) and military service, (15 yrs. US Navy), our family has moved 15 times in 22 years thus far. I understand our situation (stays longer than a few months) may be up for debate to be defined as nomadic. However, I relate to most comments shared. We never know how long each stay will last. The lure of adventure is always there! I’m now starting to look for compromises ie vacations, instead of whole life pickup and go. Thanks for sharing your thoughts.
In an elected system, the representatives are to a degree self-selecting for their enthusiasm for the job. Under a system of pure, universal sortition the individuals are not chosen for their enthusiasm.  Many electoral systems assign to those chosen a role as representing their constituents; a complex job with a significant workload. Elected representative choose to accept any additional workload; voters can also choose those representatives most willing to accept the burden involved in being a representative. Individuals chosen at random from a comprehensive pool of citizens have no particular enthusiasm for their role and therefore may not make good advocates for a constituency.
