A few things wrong with this in my opinion.

1. If simulation of a mental phenomenon is not equivalent, in essence, to the phenomenon itself, then what's a meaningful difference between the two? What is this elusive essence of the phenomenon and why is it a requirement in any meaningful definition of intelligence, consciousness, sentience, etc? If we build a silicon brain some day that passes as human, does it matter that its essence is different from a carbon-based brain? 2. Searle's Chinese Room neglects to acknowledge that the room itself is what would be exhibiting intelligence, not the homonculus within. His argument fails by presuming without evidence that consciousness is not an emergent phenomenon. 3. Of course we don't expect the computer to urinate on the desk, just as we don't expect a silicon mind to produce serotonin. That's irrelevant to the question of whether or not it exhibits the qualities or behaviors that we associate with consciousness.

I guess I just don't understand why there needs to be this added, untestable, metaphysical requirement attached to all of these words. And my question to those who suggest this is, what would it convince you otherwise?
