Karam, the simple answer is that buying a DVD costs me about £2, paying for a streaming service would probably cost me about £15 per month. I so rarely watch films that it is cheaper for me to buy the physical disc and can play it as and when I please....without having to rely on a third party like the internet to allow streaming.
If I subscribed to a streaming service, I would kind of feel obliged to watch any old tripe just to feel as though I'm getting my money's worth, best I stick to buying discs
If I enjoy the DVD film then I'll keep it for watching again, if I don't enjoy it I send it to the local charity shop.
Oh, just to put you right on one matter, you say you don't technically watch a film....yes you do....according to the Oxford English Dictionary at least....my bold below....
film. noun.
sense 10.
a. A representation of a story or event recorded on film (sense 9) or, in later use, in digital form, and shown as moving images in a cinema or (latterly) on television, video, the internet, etc.; a motion picture, a movie.

PS: Kinematograph (meaning "motion picture"). Actually it translates as movement in writing, by the hand. The Greek termination graph was used to form adjectives, sometimes in the passive sense of ‘written’, e.g.
αὐτόγραϕος written with one's own hand,
χειρόγραϕος written with the hand; sometimes in the active sense, ‘that writes, delineates, or describes’, chiefly used
absol. as nouns, ‘one who writes, delineates, or describes’: e.g.
ζωγράϕος a painter from life,
βιβλιογράϕος a writer of books,
γεωγράϕος a delineator of the earth, a geographer.
