In the US, you do not need a residential address; you need a domicile. Your domicile determines e.g. what taxes you pay, and where you register your vehicles. You can't opt out of taxes ;) Your domicile can be a family member's or friend's residence, or you can pay a company to provide you with that service ("Commercial Mail Handling Agent"). I "lived" in a mail cubicle of a service provider company for some 3 years, while driving around the country in a motorhome. For bank KYC rules, the bank's automation may recognize and refuse prominent companies like that, much like they refuse PO boxes. A human may sometimes override that decision. That's unrelated to definition of domicile, and banks will generally also accept KYC information for a family member instead. Or you plan ahead and get KYC'ed before you move into non-traditional domicile situation.
