I download pretty much anything I fear is controversial and at risk of being censored by the host, removed by the creator, or edited at a future date. I dedicate a few dozen terabytes of storage to store these things. I have several YT channels with >300 videos archived and routinely keep them up-to-date with new uploads. All because a funny video one time was deleted after the creator received a copyright strike for approx. 3 seconds of audio on the video. The average person isn't going to know how to use a command line program to download a Youtube video. The average person also doesn't have enough space to maintain large and old archives. The average person wouldn't care to maintain and prune an archive for relevance every now and then. And even if you manage to get the average person to care about all of this - you still face the hurdle of there not being any "official" hash to compare to.
