> For one thing, this approach seems to inherently conflict with the fact that you can link directly to a particular timestamp in a YouTube video, either in an external link using the `&t=...` URL parameter, or by just including a timestamp in a YouTube comment.

The more I think about this, the more I belive that this is literally the only reason that ad blocking cannot be meaningfully defeated for video on emand. Because of the concept of referencing a fixed point in the video by a time stamp, there will always need to be a mechanism to offset the time stamp with respect to the injected ads, which, in turn, gives ad blockers the ability to find out where the ads are exactly.
