This sounds like a non-starter to me. Alternative established video services already exist and struggle. IF you could take on YT it sounds like you'd need to disrupt it (according to the original definition of disruption). In other words for this case find an under- or un-served market niche where the features of your product matters and can compete and win and then expand _somehow_ from there. If I understand correctly Vimeo differentiates itself by offering features that matter to more premium video creators. Who cares enough about decentralized uncensorable video distribution to use an alternative non-YT product? What do they need or want? What business model can work when offering a service to them? These are the business issues. On a technical side, fully distributed video storage and streaming sounds like it has a hefty set of technical challenges.
