Buying a DVD is surprisingly similar: you are buying two things, you are buying a physical copy of something (i.e. a movie which can be played) and a perpetual licence to play it in certain limited circumstances.
Even though you 'own' the DVD you still don't get to do what you want with it - you can't do public screenings in the UK for example without further permission.
And even though you 'own' the DVD might not even be able to copy the data to your own laptop for personal backup, again depending on jurisdiction.
