In chrome I can just right click the text, keep right mouse held down while I use left mouse to highlight the text I want and then lift right mouse while hovered over my newly highlighted text and select copy. This method while overkill is easily circumvented in the provided example, without even killing js or using developer tools, it could possibly be fixed with a larger covering item, but really if you don't want people copying your text, use a library to render it as an image.
