I don't think the majority of people care about owning music anymore.
It's not as clear cut as you think, total income from all digital music (combined downloads and streaming) only caught up with income from physical sales last year so more people are still buying music than streaming.
In 2014, the industry’s global digital revenues increased by 6.9 per cent to US$6.85 billion. For the first time, the industry derived the same proportion of revenues from digital channels (46%) as physical format sales (46%).
