It's a rule of thumb for "normal" cars.
If anything it takes less power to stop just as fast as you accelerate because of this wonderful thing called the atmosphere.
The problem is that stopping as fast as you accelerate is still too slow to be satisfactory in a lot of cases.
On low end cars that don't have enough power to roast the tires at any speed in any gear you need more braking power than engine power because you need to be able to use 100% of available traction to get from 60-0 for obvious "think of the children" reasons.
Nobody cares if your Yaris doesn't have enough engine to use every available bit of traction to get from 0-60.
Basically "you should be able to brake 30% harder than you accelerate" is a good rule of thumb for economy cars.
When you start talking high horsepower to weight ratios or other vehicular "extremes" rules of thumb don't really work.
