> the content I purchased [...] is required to allow me to download it

This would work if laws mandate that media like movies, eBooks, music must be downloadable DRM-free by purchasers, which will probably never happen as the entire industry is built against peer-to-peer file sharing and media piracy.

The industry likes this model but the consumers do not. They like the convenience of having all their media in a single nice UX like Netflix, PlayStation store, or Spotify. They do not like that profits are usually directed away from creators, and that "ownership" in these stores is more like temporary licensing of DRM content. This is where a new economic model could be introduced to fund some media production and distribution - for those creators and consumers willing to embrace it.
