Why don't patch components completely replace traditional components, just like computer motherboards, there are still traditional components?

The patch element is small and easy to integrate, which is its advantage, but its disadvantage is that its ability to withstand high voltage and large current is very weak, and its capacitance (referring to electrodeless type) is very small, which can not replace large capacitance; Most traditional components on the motherboard are capacitors, right? In fact, this kind also has patches, just stitch patches, and the size is not small.
