Using adblockers is a safety measure.
Since ads on websites today are known to spread malware and the ad industry has not been able or is not interested in fixing this I don‘t see any value in discussing your idea.
It's not the advertisement industry's job to fight malware or to protect you from it, it's their job to get products and services sold. That's called capitalism.
Also, if adblock is a safety measure, why then do these adguard filters and adblockers block ads/trackers on legitimate sites like Google and YouTube?
There are no "safe" places where an ad blocker can be disabled because these ads aren't strictly contextual. Any ad could run on any website.

In other contexts we would call this "aiding and abetting".
