So it depends on whether or not you have enough money. As cherdano points out/implies, it isn't a great engine if you draw it all out with no source of economy to use it. With that said, gold isn't always the answers to getting money. Obvious but important. If there are cards like coppersmith, bank, or any other ways to earn money, suddenly gold isn't as necessary (because BV/Wharf should have a lot of extra actions to play with).
