Is rewiring worth it considering...

My question surrounds rewiring. Why bother?

Let me explain my point by following a signal path:

First, a nice thick speaker cable connects to the terminals. But the second it crosses the terminals threshold, a thin little circular spade is sandwiched between 2 screws which is attached to a rather thin wire. This thin wire goes to the crossover (again attached with a thin spade) which is then distributed across a circuit board that is even thinner than the thin wire, into caps and inductors with non copper ends, etc.

From here more thin stainless steel spades to wires and onto the actual drivers, again spades and then an very thin wire into the actual driver itself where the wire spun around the voice coil is thinner than every part of the signal path so far.

So, long winded, but here is my point: why bother rewiring when all you will end up with is a point where the internal wiring will get very thin and you cant do anything about it?

Isn't this akin to having a 40 lane highway bottleneck into a 2 lane road when it reaches the woofer's voice coil?
