I think it's going to be a war between google and the developers of ad blockers (kind of like twitch and how they are fighting ad blockers too). And isn't chrome removing ad blockers in their extension manifest v3?
I guess if the worst happens, google could require everyone to have an account with a valid phone number to view videos and ban anyone using an ad blocker. But then there will be plugins made to mute ads automatically. There will always be a way around it.
