Even though I love leather belts, but IMO, this ancient belt design is obsolete. It is good as a beautiful dress accessory to impress ladies, but for carrying things like gun, knife, whatever on the waist it's better to go with a military style synthetic webbing designs. They are much more versatile.

However, if you need to just keep your pants in place - you can perfectly survive with only 4-5 ft of paracord instead, using the rest for real survival needs. So, a woven paracord belt is not that bad idea for the cord storage.

By the way, the belt on the image can be fixed with a much smaller piece of the cord, in case you need to use the rest of it for something.
