That's offtopic. Some random website does not have the right to force me to run any particular software simply because I requested a page.

Nobody is, and I never claimed anything like that.

I'm saying that publishers don't get to simply invent new law. Contracts have hundreds of years of history, and they require certain elements to be present.
> Infringing on the publisher's rights
No rights are being infringed. You are simply refusing to understand that their rights end after they hand over the content... unless they have a contract that says otherwise. Sorry, but just because you don't like the doctrine of first sale and wish it didn't exist doesn't mean you get to make up "rights".
If I write a creative work, I have the right to not give or sell you a copy, and I have a temporary monopoly granted by the government that gives me the right to decide who can reproduce my work. I absolutely do not have the right to decide what you do with that work (besides making copies) once I hand it to you.
The self-entitlement is on the part of the publishers who want to invent a new right that covers use.
Note that publishers can try to detect adblocking all they want, and use any results of that detection (or lack of results) when they decide if they want to send me anything. The catch is that there is no guarantee that their request that I run a particular script, or that I even have a Javascript environment to run that script in the manner they are expecting. I suggest that it may be a bad idea to base your business model on an unreliable source.
As for "justifiable" - the advertising industry and the publishers that involve themselves with the ad industry are not exactly standing on moral high ground. If they don't like the hard line some of us are taking regarding ads, they should consider why we are doing so. Tracking is a malicious attack. Live by the sword, die by the sword.
