Obviously everyone has their opinion and is entitled to express it. I just want to represent the argument that the OP is dead wrong and that it's past time that Apple started removing the optical drives from its laptops.
The optical drive is the second biggest and heaviest component inside laptops besides the battery and the laptops can be made substantially thinner and lighter by removing this one component. It is also probably the single most failure-prone component because it spins, it is open to the environment, and it accepts foreign objects. So some people above have made the argument "well wouldn't you rather have it than not have it, what's the downside?" The downside is that it adds size, weight, and a higher probability of failure.
So if you you only rarely need to use an optical drive, why would you want to schlep it around with you constantly? I'm not doubting that there is a very small subset of people who need to burn disks all the time, but it's definitely a minor minority. For the vast majority of people, email attachments, Dropbox, Google Drive, and USB flash sticks are the
preferable solution even if they have an optical drive built into their system.
I've had a 2011 Macbook Air as my primary computer since launch, so yeah I've had to find alternatives for the 5-10 times I've needed to burn disks. It has never been inconvenient. I don't think I'm a rare case when I say that there are still plenty of computers around my house and office with disk burners that I can use. There's also Apple's external Superdrive, or if you don't want to pay the Apple premium you can get generic slim USB DVDRW drives for $30.
Which reminds me of another point: if I was burning as many optical disks as you people claim, I would still prefer a laptop without an optical drive because I would want to use a desktop-size external burner anyway considering they are very cheap and 3-4x faster than the slim mobile ones.
Which is all besides the point that Apple for some reason is still selling the ancient 15" Macbook Pro chassis that still has the optical drive so these complaints are stupid.
