Convenience isn't a goal, per se. It's a by-product of sorts. When things work and are intuitive, they're very convenient. Economically, it can be useful to design many things this way.

A good doorknob is ready-at-hand: it's just about invisible to me until it breaks and, suddenly, it's present and bright in my mind. I've been in the woods and become unsafe: everything around becomes suddenly, viscerally present. That's not a feeling I want often. But individual things I attend to (like watching what I eat or trying to ID a bird by its song) make the world much more colorful, and make me feel more a part of it. Plus, as the comments here suggest, immediate convenience can lead to downstream perils (e.g. in terms of data collection).
