Yes, it is very good. I can very much picture the Original Series continuing in that fashion had it been allowed to complete its run.
As for the money situation, I've always viewed it as the FEDERATION doesn't use money internally, but there must be some form of trade-able requisition unit, as any organization would need something like that to facilitate resource allocation. However, the Federation would not be able to force its tenets on unaligned or independent peoples. Therefore, to trade with non-members, like the Ferengi or Klingons, the Federation would still have to keep vast stores of Latinum or whatever a race used for currency.
