I would totally agree with you on one point: accessibility. Protecting text published on the web means that you have to obfuscate it one way or another. Therefore, if one is really serious about protecting its intellectual property without diminishing user experience, one has to associate its protected text with an audio version.

For the rest, it is true that most copy protection scheme are pointless for many technical reasons.
But at CPROTEXT, we succeeded at designing a unobtrusive solution that can protect texts from copying/pasting and web crawlers together using only HTML and CSS code.

I won't drop a link here since I know it would be considered as incorrect and spam, which I fully agree with. But if you are interested in a javascript-free solution, only based on web standards, look for our online service on your favorite search engine. You'll find an example page where you'll be able to test by yourself.

PS: I filled the "website field" of your comment form with the URL of the service, feel free to remove it if you think it is inappropriate
