Let's not take things out of perspective.
I was replying to:
Considering that replacing your fenceline costs 0 gold, the only way his wish that replacing shouldn't be more expensive than refreshing to come true would be to lower the cost of refreshing to 0 as well.
If you replace a 100 fences, you'd lose the gold from selling those fences. It's cheaper to replace fences than refresh them. Refreshing is a lot faster, but takes gold. But you could sell the 100 fences you have, thus getting some of it back. Replacing the whole fence line would be more COST effective, since you wouldn't spend any gold, but then again, would take a too much time.
Everyone else got it, don't be an ass..
