Let me try to reword my point. Imagine a dominant could put a chip in your head that would ensure absolute, instant obedience to any order he gave you. Which would have more value: your submission with or without the chip in your head?
I'd say we're right back to the "to each his own" point with this. Value is determined by the consumer, in this case the Dom. Perhaps the Dom doesn't really care how or why tasks are accomplished so much as he cares that they are indeed accomplished. For some people, it's not the motive at all that's valuable, it's the end result.

I'm inclined to agree with you on a level of personal taste and priority, but phrases like "true value" or "a good Dominant" are simply not universal.
