Currency issuer targets the stock market?

We can do that with a simple rule change, standard exchanges can issue the green back via marginal lending among the pre-qualified stock traders. The Fed edicts the issuance rate, all stock markets have a qualified margin bank that issues greenback according to the transparent rules.

We can do this in the sandbox, not a problem.  We get a banking structure backing the various stock markets, probably works and, oh by the way, you just invented a new sandbox company, Roger Farmer.  We don't need to issue currency, we need liquidity license from the Fed, the right to give the various bots running margin banks power of attorney.  The bot will be representation the Fed.
