[Star Wars] Why aren't robotics and cybernetic implants more common in criminal and military settings?

Luke's hand is at least as good as the real thing, and the technology is obviously there to make it way better. Look at General Grievous.

Now Vader's huge cybernetic transformation could affect his force powers (maybe), but why don't regular folks and those who fight other humanoids make more use of this technology?

1. Cost. Vader had the benefit of being saved by the goddamned Emperor of the galaxy, for whom cost is barely a concern. Most folks do not.

2. Religion. Even those who don't believe the Jedi had the magical powers they claim often believe in the Force, and that it flows through *living* things, not droids or cybernetics. Many people consider willingly taking on cybernetics to be like excising chunks of their own souls.

3. Pain. We...do not have fantastic anesthesia, here. This operation will hurt.

4. Widespread interference. Many smugglers and bounty hunters and the like do business in places where electrical interference would disrupts the control circuits of cybernetics. This is by design, as those same conditions make tracking more difficult.

5. Discretion. Since cybernetics aren't common, wearing cybernetics makes you stand out. For all their loud and brash style, most smugglers and other criminals have nondescript civilian clothes stored in case they need to blend in. A giant glowing robot eye will make that harder to do.
