Adblocking is an arms race. Google is handicapping adblocking progressively the fact that it doesn't take one day to achieve absolutely doesn't make it a myth. Adblocking is technically worse and the more locked down our environments are the easier it will be to kill or drastically reduce it.
If everyone had the same attitude this would probably already be the case.
I'm extremely intolerant to ads, so I would leave Chrome if ad blocking stopped working.
