Why does a failure in a single, critical component often end the mission for a distant modern space telescope?

The cost of sending a repair crew or autonomous drone is currently prohibitive.

Because sending repair assets millions of miles out to distant locations like L2 is cost-prohibitive, modern space telescopes must function perfectly with their fixed configuration for their entire duration.
