You'll need a lot of money just to store it then. If that's what you want to achieve then you should use something like IPFS or Torrent instead of blockchain, that should give better speed while not compromising security that much.
That should be able to somehow fix the censorship problem too.
Yes a torrent is ideal for distributing the files but it's not the same as having the video playing right out in the open with the viewers posting comments and maybe even participating with the content creator if it was something like Youtube's "Premiere" feature.
I don't think we can ever have a truly decentralized Youtube clone that can be ran on only mobile phone sadly.
