Actually the point was never that it is not useful. Having a toaster built-in to a laptop would also be useful, but the tradeoffs are not worth it.
The issue is whether the space & cost is net-net positive: my point is that it is not. What would be more valuable to the largest group of MBP buyers, in my opinion, would be (and not necessarily all together):
- Better battery life
- Smaller/lighter
- Cheaper
- SSD (fast) & HDD (slow) storage
We'll see if any of those come to fruition...

Does that matter to you? The point is that the optical drives are still useful and that by using multiple Macs at once you can read/write to CDs/DVDs using each of the machines and get the job done much quicker than with a single Mac.
If Apple removed the optical drives then the effective price of Macs would likely go up as they'd likely keep the US price the same, but charge for the external optical, not make it an included accessory.
I'd also rather not have to carry around an external optical drive.
