> How do you know that the user uploading the file actually owns the rights to distribute the file?

While I appreciate that BitTorrent files are technically used to distribute some "legitimate" things, even in those cases the people you are talking to are part of a swarm: like, the premise is that you are paying someone to have helped you get more of a file you are downloading that everyone has agreed shall cost nothing (whether or not it actually does), not that you are compensating them for the file itself (which would have value above and beyond the bandwidth and cpu costs).
