If I understand right, you don't want people to be able to highlight text on 
your website and copy it (ctrl+c).

Solution: Don't try.

This is not a Rails limitation. This is you not understanding the implications 
of the Web in general.

Have you disabled right-clicks? If not, all someone has to do is highlight 
text and right-click->copy.

Do you know what browser your users are using? Different browsers do this in 
different ways, and some don't do it at all.

What if they're using wget? You could block the wget user-agent -- in which 
case, the user can just use the --user-agent commandline option.

What are you going to do about file->save as?

What about packet sniffers? Is every single request going to be sent via 
https? What if the user's behind a proxy?

There are all kinds of tricks you can do, and every single one is security 
through obscurity -- which means it's only a matter of time until someone 
figures out a way through.
