There are other approaches. For example, the government could declare that certain commodities could only be purchased with the currency. Oil, for instance (and there's precedent there, too). Personally, I think the government declaring that basic incomes will be paid in the currency is enough, but I see no reason to disallow other methods. Another example is to do what the dollar says: this [currency] shall be legal tender for all debts, public and private. Another one would be that banks could only accept that currency, and make loans in that currency. There's a lot of options, but you're right: we'd need to get creative about it. As CS people, that's basically our job description and it's a good challenge, and I think, a solvable one. Thanks for your comments, I do appreciate it. I certainly don't have all the answers.
