It's more so that you are allowed to try to block ads. If YouTube adds DRM or otherwise manages to stop usage of ad blocking, they are completely in their right to do so.
IIRC if something runs on your system, you have the right to mess with it, however you want — e.g. block specific parts of the site, or use reader mode etc.
If youtube does that, I will stop using the site and wait for a workaround to be written. You could preload the videos and cut out the ads, for example.
