Disclaimer: I'm not sure if this question is appropriate for this site, Travel SE, both or neither.
For a great many amenities which are useful to most people (e.g. bank accounts), you need to supply a "permanent" address of some kind, and oftentimes Bad Things will happen if you supply an address which is either not available or unreliable: For example, at least in the UK, banks will freeze your account if your post is returned to the bank as "undeliverable", and the excitement of living a nomadic lifestyle will be somewhat dampened when you're e.g. in the middle of the Mongolian steppe and can't speak Mongolian/Chinese/Russian and suddenly have no money.
For someone who wants to lead a truly nomadic life, then, what are the solutions to the dilemma of needing a geographic address for e.g. banks, insurance companies, etc.? Family and/or friends are always one possibility, but are there no solutions which are more "professional" and/or "official" so that said persons don't need to be responsible for my stuff?
Finally, in some countries, it is required to "register" your primary residence in some way; Although this can obviously be more difficult than dealing with private companies, is there no solution for this, e.g. some way of "officially" being on the move? Of course, solutions to this, second and more specific problem will likely be country-specific and so may be too broad to answer.
