I'm repeating what other have said, but yes owning what you like is worth it. I've watched my sets of Venture Bros. DVDs, both Tron movies' Blu Rays, Star War DVDs, Alien Blu Rays (now I need to find some helium filled container to hide the VHS copies of the last 2 in) way too many times. Also, many Blu Ray makers are getting smart and giving you the DVD copies in the same case, giving you the incentive to sell you old DVD if you have one or giving you the relief of knowing that any video frisbee player (besides laserdisc, you nutty collectors) in your house should be able to play that new movie you just bought. There is also the fact your internet could give out right when you want to download something. Having at least a few physical choices is good in cases like that.
Netflix rotates it's streaming shows and movies out of circulation either for rights issues or space issues all the time. Other streaming and digital sales service have the same issues with server space and the content creators (specifically greedy execs) wanting more money. The only reasons I trust Steam and GOG are the sales and the fact they screw over their customers the least compared to most other media companies. I'm still extremely hesitant to buy full games and movies via download from any other company because of the DRM systems failing at the perfect moment and giving me a headache, the console becoming so old the servers are unplugged or the possible lack of support if the service looses distribution rights to something I payed full price for.
Also, the physical discs always have at the very least some extras (unless you dug it out of the bottom of the bargain bin) but usually have captions (usually in multiple languages), creator commentaries, production documentaries, and sometimes games, Easter eggs, or extra video shorts expanding on the movie's universe, maybe even dropping sequel hooks. Netflix might have captions in more than just English, but I've never heard of even the commentary tracks being available for anything they stream (besides House of Cards. But I don't care about House of Cards). They also don't ship both discs if the DVD you ordered would normally come with an extra disc with all the special features. You might be able to find some making of documentaries online,[footnote]Youtube's automatic IP protection, in all its draconian DMCA banhammer swinging, doesn't seem to care about these popping up when there's honest reviews, LPs, and even actual rights holders to false flag.[/footnote] if you can find them.
