"The best way to get a bad law repealed is to enforce it strictly"
Demonstrating that the rules are broken by creating unreadable code that passes the readability guidelines seems a fair demonstration!
As for line lengths, while you can rotate monitors by 90° without too much effort these days, most guys I know work on an unrotated 16:10 or 16:9 monitor, so long lines are actually not that bad.
90º monitors / 9:16 aspect FTW!! I use a 1920*1080 and a 1440*2560.
Also, when using a 16:9 aspect, I always split the IDE down the middle so I can see two files at the same time
No need to strictly stick to the traditional 80 characters (as derived from when we coded via terminals), but it's still a good idea to resort to line-breaks after some point.
