I don't see why there can't be a way to download vids directly from creators with micropayments. That way the user gets something as it was intended. If there was some kind of link that could go in the vid description, it would be great.
I suppose re-sharing would be the problem - but that may only occur in some instances. And it might not happen immediately either. If it does happen, if there was a way for creators to collect tips, that'd make it more feasible if their videos spread far and wide.
