NOTE - 2021-05-24
-----------------

The script below isn't the fastest way to copy-and-paste from a protected 
Google Doc. Before trying it, I'd suggest following MikoFrosty's advice from 
the comments:

1) Change the end of the document url from `/edit` to `/mobilebasic`.

2) Disable Javascript (as described in steps 2 and 3 below).

3) Keeping the console open, reload the page.

That should be enough to allow you to copy freely. The script here is 
*probably* only necessary if the /mobilebasic view isn't rendering something 
correctly.


HOW TO USE
----------

1) Open the protected Doc using Chrome. Scroll all the way down to the bottom 
to make sure that it is entirely loaded.

2) Open Chrome Developer Tools (<Ctrl+Shift+I>), and click "Console" to open 
the Javascript Console.

3) Open the Command Console (<Ctrl+Shift+P>). Type "javascript", and select 
the option "Disable Javascript" when it appears.

4) Copy the script below into the Javascript console.

5) Leaving the Javascript Console open, you may now copy-and-paste from the 
document as normal. (Some formatting may be broken. Closing the console may 
re-lock copy-and-pasting.)

6) (OPTIONAL) To copy the entire document as plain text (no formatting), type 
the following into the console: 

    document.body.innerText

The text will be loaded into the Console itself; copy it by clicking the 
gray-highlighted "COPY" at the end.
