Are you claiming that you set your rim brake pads as close to your rim as your disc pads to your rotor? Please think hard before you answer this.
**EDIT: A better way to say that would have been "I don't think we are not talking about the same thing". From your response you seem to think my post is weighing in the relative merits of disc brakes vs rim. It is not.
No, I didn’t miss your point. Your and Alo’s point are wrong. I don’t need to set my rim brake pads as close to the wheel as a disc rotor pad needs to be set but the pads generally need to be set closer than most bike shops will set them up initially. The reason is that a rim brake takes less clamping force as you pointed out In
Yes, a 26” rotor would require much less clamping force than a 6” rotor.
A rim is just a rotor. Bicycle can generate enough braking force with rubber pads and calipers that are set further away from the rotor than hub mounted discs can because of the size of that rotor. The maximum braking power is at the point where the bike is just about to rotate the rider around the center of gravity, i.e. doing an endo. Any front brake that is properly adjusted is capable of doing that. Detune a hub mounted disc to the point where it takes half lever travel to get to the point where the pads contact the rotor and see just how bad a hub mounted disc can be.
