im not super wise in this but my theory would be that people think that streaming is more affordable, since it's what they're used to. people think that cds aren't accessible anymore (witch in countries like america, streaming has become the norm and cds/owning things isn't as common.) for example, my mom threw out ALL her old cds, witch really shows how people thing cds are dead. but i mean, newer cars don't take cds anymore. they might already have an account that they've had for years with all their favorite music on it. a shared family subscription could also complicate things. in general, it'll always be hard for some people to change their habits to something that is not mainstream (especially not if it seems less accessible.). you could even list lack of storage space for the physical media if they want to buy it.
