Same reason I value home made cooking, home made furniture, and my kids drawings. Not everything is about the result itself. The process is important to me. Knowing that there is a human on the other side matters. In fact, learning that there is/isn't changes my perception entirely.
You didn't really answered my question. Why is it important to you to know that there is a human on the other side of things? You just restated what your preference is without giving the 'why' of the preference, which is what I'm curious about.
