I enjoy cooking and baking but even I would say that the only argument needed for "outsourcing your entire meal prep and having food delivered to your house" is "I don't feel like doing it myself."

I'm not posting this just to be a jerk; rather, I think that too often we spend time trying to justify a behavior that is not at all damaging, but somehow seems "bad."

If you don't like doing X and you can afford to pay someone to do it, then go ahead, do so and get on with Life.
