I suppose it depends on your definition of "hefty" but a couple of thousand USD is usually sufficient, depending on jurisdiction, and obviously is expected to pay for itself many (, many, many) times over.
It's not that hard and it's not just for the 1%. Especially if you're anything approaching a "digital nomad" I can't think of any reason why you wouldn't establish a consulting company somewhere offshore, bill from that, pay yourself a quarterly dividend and then import only the money you actually need.
