All it shows is that there is certain group of people which will pirate even if the content would be given for free.
The people that would view paid content should not be punished with DRM, that only works on certain platforms and certain browsers.
It actually makes pirated product much better than original. Pirated videos besides being free work on all platforms, you can view it on your computer, phone, tablet. Living or visiting a different country does not revoke your rights to see it, and you can make as many copies of it as you want.
Whether or not piracy is a problem is immaterial to the importance of DRM if DRM has no effect on piracy.
