Mechanical advantage is not the only reason one would use a pulley. For instance in a car, pulleys are used to drive alternators and power steering pumps. The use of the pulley and belt is to give power to these devices from the crankshaft. It's a method of transfering kinetic energy to these devices.
Pulleys make lifting things easier. example: If you want to lift 100kg you don't want to lift it with your hands, so you use a pulley. The best choice would be to use a pulley with 4 wheels. Using this would make the effort to lift the 100kg about 75% easier. So lifting the 100 kg with a pulley would make the object be about 25 kg. That is why pulleys are important.
A catapult is probably more effective, though a pulley is easier and safer to use.
