The traveling salesman has no use for my local work, as he will be gone the next day, and can't even find me by then. When gone he might never come back.
Any traveling salesman who wants to prosper will specialize in crypto or local currencies that have credibility in his next venue. He might trade local notes to pay for local expenses.
OK, you already plan to base it on other money systems, it is only for use as "physical cash", not "currency"? And you must accept all the aforementioned kinds of irregularities?
