You can buy a DVD today still, also, even if you're talking about something that is streaming only, buying a subscription to a service is easy. If you don't think there's enough value in it, that's a different conversation.
Setting aside that some physical media does come with a digital download/digital code/whatever, or that you can just purchase digital media direct, or that you can just use use a streaming service on your phone/tablet, if you look at the top of this thread, we're talking about "moral justification" for piracy.
You're not suggesting that the small hurdle required to clear before you can watch a DVD specifically your phone or tablet justifies piracy beyond you just not wanting to pay for it, are you? If so, you're making OP's point...
Also, using handbrake is not "way more difficult/time consuming than a torrent", come on.
