I can see your argument, but on the other hand I look at the example set by digital audio. The same balkanization occurred there, until finally things got so bad that finally the media caved to pressure and now I can finally buy legal audio in formats that really are interoperable. There were several lousy years where I basically gave up buying new music while the industry figured out that the reason I wasn't buying what they were selling was because DRM didn't work for me.
So there is precedent that delaying adoption of really interoperable DRM has resulted in better media access in the end. On the other hand, I can't think of any precedent saying that having relatively painless DRM has resulted in better media access. Of course it's possible, but I think precedent weighs against you.
On the other hand, maybe you're right and the battle is already lost; with digital audio it was really Apple's closed distribution model that finally broke the camel's back-- there was no way for anybody except Apple to encrypt music for iPods, and music encrypted for iPods wouldn't work anywhere else. Nobody was able to put together a deal that would bridge that gap, and although Apple's market share was significant it wasn't big enough to standardize the entire market on, and consumers knew that they would be screwed one way or another if they opted for any of the then-available DRM flavors, so enough of them stayed out of the market that eventually the markets were forced to open up. With digital video, that hasn't happened. All of the major media playback manufacturers support the same DRM flavors, so most of the market can be served with relatively little pain.
On the third hand (ha ha), while I have started buying music, I've stopped buying videos. I bought a lot of DVDs after CSS was cracked so I could actually play them on my other devices; it was essentially an interoperable format in practice if not in law. I stopped when Blu-Ray came out because DVDs became second-class citizens, but Blu-Ray was too locked down. Streaming rentals work for me because the DRM only has to work once, but I'll never actually trust that streaming companies will still be there, supporting "my" content years from now after they've made their buck today.
So I still think that there's an effectual struggle to be made, that there's a chance that big media can be convinced to accept open standards. I'm not super optimistic, but I think it's possible, and so I'd oppose any attempt to make DRM more seamless and interoperable for the masses (easy for me to say, since they never seem to interoperate with MY devices anyway. Hazards of running Linux I guess).
