Gold works for accounting. It maintains a static money supply. Fractional-reserve can provide expansion.
Gold works with the existing dollar. Federal Credit Receipts allow it to be tried in a city/region and roll it out over time.
The trick would be to revalue gold periodically (perhaps monthly) and all the products backed by it. One thought might be to issue dollars, with gold setting prices on producers. Producers can collectively decide on prices. As the economy grows, producers would lower prices once/month.
