Nobody is going to go to OP's personal site to watch videos. They are going to fire up YT and eat what the algorithm feeds them.
The reason PeerTube and Nebula are important is it provides the potential for a true alternative destination for people looking for videos. Once these platforms have an enough content to draw an audience naturally, then content creators will be able to survive a post-YT world.
For people like the OP, it's probably best to follow the model video games do with DRM. Post on YT first, to get the ad revenue, then repost on other platforms after some time to build up an alternative subscriber base. Presumably, in-video sponsorships will pay for these views as well, even if there's no direct ad-sense like revenue model.
