If I look around at porn sites most have no DRM. If the sites have any limitations at all it's an "all access" model that allows you to stream all you want with a set number of DRM free downloads per day, week and month (depends on the site).
In terms of traditional media like movies... physical media is easily attainable and available to users as an alternative to Netflix, Amazon and others giving you an offline copy that cannot be revoked after you purchase and "own" it.
Buying a physical copy for JAV is also possible especially if you're in Japan but not practical for anyone living outside of Japan given the unwillingness of major Japanese retailers to ship pornography outside of Japan (understandable) and the cost of smaller boutique import/export businesses who offer the service is often high if they offer it all....
I have a fairly large R18 collection, it would be nice if DRM was removed or lessened somehow especially since everything seems to escape on torrents but I doubt that's likely to happen. I agree with
@Walle12 for certain things like VR it would be super helpful if that specifically had less DRM or more player options so you can fine tune it. I don't watch VR porn but I do play VR games and so much comes down to adjusting settings.
