Then the problem is that streaming needs improvement, not that the consumers should be wasting cash propping up a failing system and filling their ever-tinier homes with tat. If only people who actively specifically want DVD/BDs buy them (which is happening already for most people below a certain age) they'll all end up going up in price across the board and even SEs will be viewed as 'CEs' to a certain audience for whom SEs are unaffordable at any price. And this is why I have such a massive, massive problem with Manganimatsu's strategy of specifically blocking streaming - it's squeezing the poorest people more than anyone. I see that Jerome is still exploring this problem now and I really hope he starts listening to the right people and does the right thing. We've come on leaps and bounds with streaming over the last few years and surely, surely it's not rocket science to get it all working sensibly eventually.
I have to say that expecting all shows to be available forever is a bit unrealistic. I understand the argument that the lack of a permanent archive copy is damaging - and I agree with it. Knowing you can always go online to watch Haruhi wherever you live, no matter what is what we need to work towards. But the way media is licensed is such a colossal mess right from, from television and radio right the way through to the home video releases (via the BBFC and friends) that it's not something anime can hope to conquer on its own. I'll be very happy if there's a global sea change on media licensing before I'm dead of old age.
