Why can transistors be so small, but resistors capacitors and other components are comparatively large?

You can make tiny resistors and capacitors too, if you accept the fact that they also have a tiny resistance or capacitance. Such things are just considerably less useful than tiny transistors. Transistors are switches, switches allow binary logic, binary logic allows computation.

However, every commonly used computer *does* have billions of tiny capacitors: that's what modern RAM is made of! Every bit of memory is made of a transistor-capacitor pair.
