The three most important reasons, for me, are:
- immediacy/ease of use: It just works and I can find what I want easily. I value my time at roughly $200/hr, so it's easy to justify ~$10/mo if it saves me even 3 minutes of my time.
- availability: I don't need to have terabytes of local storage because I can just stream whatever I want, whenever I want.
- patronage: This is the most important thing for me...I want to pay for content. I think the industry has, by and large, behaved like spoiled toddlers for the better part of 2 decades now, but that doesn't make it right to not pay them for their work. And I think I'll get better content if I pay for the things I like.
