Currency has to be backed by something. That something in my mind would be creatable, sustainable, and reproducible. The human labor capital of the two hours a day would be how you would essentially earn and create a currency. Everyone puts in their best for a short time without no payout until a sustain supply is produced in about three years. This eliminates debt, gives you a bulk sum to build new infastructure, and sets up payments for citizens to choose a full time position in what they had previous spent two hours a day working on. Builds upon itself. The drawback is this: people will be assigned according to what they are skilled or exceed at not what they choose to pursue. It isn't capitalism and it isn't free will. If you excel at accounting that would be your job over say artistic ability if your scores higher in accounting. The jobs wouldn't be a free market. Assigned and that's what you paid to do for 36 hours a week. I would also make the work week different doing twelve hour shifts three days a week Monday through Saturday and Sunday would be everyone off because I am religious and believe God intended for the work schedule to include a mandatory day off for rest, family, worship, regrouping. Everyone would have off four days a week to pursue their own passion, homeschool their children, do what pleases them, the other three days their mine and working towards maintaining the system. I feel like that's a fair trade. They get half their time free, plus a day to rest/enjoy their religion or heritage, and the other half they are creating a sustainable economy and living standard. Disability wouldn't be a thing, people who were severely disabled would essentially get paid to help raise awareness, help people learn to be caregivers, help people learn to love the outcasted parts of society. Think most severely disabled person you know, they can still teach another human to love. Learning that is one of the biggest benefits one can produce for a society. They would be compensated for doing what they do best, showing others what love and compassion is and proving they deserve life. A system built upon honoring life as sacred would be the essential currency backing, of course prefunded in human labor, and sustained by human capital.
