 Which of these is not a barrier to the success of a complementary currency?
New money: Do local currencies actually work? Timebanks, local exchange trading systems (LETS) and digital inventions like bitcoin can provide alternative ways for people to pay for goods and services when mainstream currencies hit crises.

It's an idea he no longer thinks will work, because the debate, since Brexit, has shifted from the currency issue back to ideas about Scottish independence. No two local currencies are exactly the same. But the Brixton Pound and other recent schemes follow the example ten years ago of the Totnes Pound, a 'complementary currency': that is, one supplementing the national currency.
