This is a great point which I just boiled down in my head to: people don't want a product, they want to solve a problem.
I think entrepreneurial developers lose sight of that a lot of times even though it is common sense.

But I think you could get a lot more out of asking why they want the hole to begin with. Are they trying to build a house to help raise their family better, or to become a better investor. Or are they trying to become better at being a contractor, which is the business they run? When you ask Why a few more times about the problem they think they have, you come up with all sorts of useful things you can help them with.
