Re: What has UGC got to do with streaming?
"...but the (very small amount of) music I stream from YouTube is to check out something..."
I have huge problems with DRM, however I do think it would be interesting to have perfect DRM. I suspect the effect on sales will be to clobber them, not enhance them. If you must pay to check something out, a fraction are going to bother. Also, if you can easily get pirated content, it doesn't concern you that much the quality. But if DRM ever got potent enough, those making the content would soon realize what they make isn't worth paying for because, ofc, very few will do so.
I think the long term effects of perfect DRM will be disastrous to content creators. If people aren't checking out your stuff, you have already lost.
This all seems rather like a paywall, and we all know how well that works.
