But here, you can't recreate Spotify from 2015. You'll never get the rights to play the music for users. Same with Netflix, you'll never get the rights to show the movies.
Same thing with Twitter, Facebook, etc. Even if you know exactly what content your user wants, you can't fetch it for them because it was posted in some other walled garden, and that wall stops you from competing.
If you want a faster horse, change the laws so that people can build faster horses and compete.
