For maximium engagement on this topic, I can't see the pay per view model working unless you expect a proportion of your audience to have watched an unpaid copy of your work. I would suspect that those who will pay will be those who already agree with your perspective. Engagement may then lead to an echo chamber with only marginal differences in opinion with regards to the core ideas.
Optional "Support Funding" of your work might be a better way to go IMHO.
Good luck, it looks like a worthwhile topic to explore nonetheless.
