I know it’s not a completely fair comparison, but to me this question is kind of missing the point. It’s like asking “Why take a cab if you know where you want to go?”
It's such a poor comparison it's ridiculous. A better analogy is "why take a cab if you know where you want to go and provide the car and instructions on how to drive"
No, it's like saying "why take a cab where you have to provide the driver so much guidance on driving as to be equal or greater than the effort of driving yourself."
