I would find having all my music on streaming EXTREMELY inconvenient. Not only can you lose access to some of it, not only are you paying continuously, but you're also locked to a specific player for this all. I do use streaming, but only for discovering new tracks. I do have a bigger collection on streaming - the tracks I like but not particularly so - but the main collection is just more convenient to have locally. I didn't download it all at once so no inconvenience here - just download a song as soon as I realize I like it enough.

Also even if I could afford to pay for my media, I'd rather buy digital DRMed downloads rather than CDs if DRMless aren't available. Not to actually use, but to correspond to the copy I do use. Specifically because it's indeed impractical, can be hard to get and and will be ripped anyway.
