You want the sink because, presumably, not having a sink - or having a broken one, or an ugly one - is a problem for you.

Are we really discussing this?

Sure, but if everyone was able to install a sink the price of getting a sink installed would fall considerably. That indicates to me that you are paid based on the rarity and difficulty in gaining the skill, not the value of the problem itself.
