That's a bit like saying there's no point in reading a book because employers don't ask for the books you've read.

The courses are awesome just for you to learn things. It wouldn't even matter if you got nothing at the end. However they do provide a genuine way to show that you've taken a course. It shows willingness to learn above and beyond your degree. You can stick it on your Linked In profile and Stack Overflow profile, it's a way to differentiate yourself from the masses.

Also it's a way of finding better employers. If you're employer is open-minded enough to take your Coursera courses seriously then they're more likely to be a good employer.
