Some websites have one column of text. Some websites have a menu on the left as well. Some websites have menus on the left and on the right.
So no, I would not need to adjust it once as websites still have different variables that would have an effect on the line width for text.
Even with good responsive design you will run into that. Iff you are saying that with good responsive design elements move out of the way of text then you aren't really a power user in my book. Because that means you are settling for a mobile design on desktop.
In addition to all of this, I simply don't want to maintain a floating browser window as that can be a distraction. I rather have the website I am looking at and trying to focus on take up my entire screen.
