Right, but you can already do that. Serve the whole page as a SVG, or JPEG, or PDF. You can already embed ads inline. Or just plain serve them from your own server, calling them article.jpg instead of http:://ads.adcompany.com/advertisement.jpg .

The reason people don't do this, is because ad companies want control. They want to know exactly how often the ads are served and they don't trust you to serve their ad all the time and to all customers. Also they want to rotate it quickly. Finally, they want to track people. So the solution is to use remote javascript. 99% of ads work this way, even mayor news sites don't sell their own ads anymore.

In this scheme, you'd probably still have ads served from a third party server. And even if they obfuscated the domain name, you could still probably identify their blob and block it.

So I'm not to worried about unblockable ads. But you're right, they will try, and I am worried about sites becoming unusable because they will emulate browsers using canvas, poorly.
