So for Robert's Vineyard, if money isn't a driving force on Earth, it's POSSIBLE that he trades his end product, bottles of wine for everything. So he "pays" his workers (who love the wine) in wine. He "pays" people to fix his equipment in wine and he "pays" for food for his family in wine.
It's also POSSIBLE that Sisko is trading his services for products to run his restaurant. His staff gets paid in a home cooked organically grown meal. His certainly had no problem putting his family to work.
It's technically possible that the entirety of Earth is ran of the exchange of favors. "You come repair my stove and stay for a my made from scratch Gumbo Stew".
It just seems terribly inefficient over having a monetary system thats based on some form of digital currency.
