A little divided here. Firstly, I agree that all the ways/tricks/exploits to get gold makes the game a little different than if one plays it without all that stuff. Secondly, however, it doesn't feel quite right that OF will simply be lost to nothingness. On its own it's not too destructive, but like with spy assisted culture wins, when taken to extremes it becomes a bit silly. A bit in the same vein really, in the current G-Major game I posted a screenshot of failgold from Moai and Hermitage, of several thousand each (it's on marathon, so costs are triple, but still), and Seraiel posted a screenshot with incredible amounts of failgold from executives. Stuff like this certainly makes it easier to get gold. But on the other hand, should everything really just disappear into thin air? There are some costs involved after all. You lose pop from whipping, or forests from chopping, and you could have put all those hammers into something else. It's not a freebie, like the gold per turn trade exploit effectively is by pillaging the resource you use to boost up the GPT.
