Obviously if you release something for free like Spotify or YouTube, few people will mess with torrents for it; but that also makes artists a lot less money. You'll never stop piracy. But laws can reduce it. And some probably-impossible-to-know portion of that reduction will pay for the legal option. 99% of people will never download qBitTorrent. It's a small portion that will even get PopcornTime. It's easy to get disconnected as more technically-inclined people, but you have to remember that most people that pirate things just Google "stream avengers endgame free" and click through the links until they find a site that works. If that gets too hard, plenty will just give up and buy the DVD or whatever.
