Earlier quoted context omitted.
But you also need to find the file first. And sites to search for files are unreliable, often get banned. I remember long before bit torrent there were protocols like napster, edonkey, imesh etc that included search function and were superior to bit torrent in this aspect. Unfortunately, bad design won.
Qbittorrent client has a built in search engine. Add the jackett plugin and you can search every public tracker in one click. I haven't visited a torrent site in years.
Not sure if the need to use private trackers can be fixed by the protocol, though. But, maybe adding a bit more of anonymity would be enough? i2p torrents provide that, but sacrifice speed. Clearly it's a spectrum and we need more "points" in the middle of it.
