That’s the neat part—you don’t. If you need anything tied to ID, passports, or legal documents, you need a legal residence somewhere. Some states make that trivially easy—South Dakota is the classic example. You spend one night in-state, show the receipt, and you’re legally domiciled for ID purposes and your driver's license says SD. You only have to physically return when your license renews. You can layer that with a business entity, suite addresses, lockers, and forwarding services—but that’s all tactics. I don’t have time to unpack the whole OPSEC model here, but USPS is here to stay. The real move is compartmentalization: minimize what must touch your legal identity and route everything else through layers not directly tied to you.
