You do that because its not an either/or decision, and the bidding nature of digital advertising means the lower effectiveness will be reflected in what you're paying. You can be paying a premium for people searching to buy gardening gloves, a little bit for people reading gardening stuff, and then a pittance for people that may be related to gardening in some fashion.
You're extrapolating based on your own actions rather than measuring the result. The results say that if you show gardening gloves to enough people at random, you'll eventually get some sales. Everything else is just narrowing down "random" a little bit.
