As soon as you collaborate with more people, 80 charactars becomes a valid target for line width. Eventually you'll have someone reading your code in a manner that is hardly pleasant with lengths of 200 characters or more:

  - Someone using a Braille display
  - Someone with a vision impairment (i.e. high scaling factor; common occurence during ageing)
  - A group of people that doesn't sit close to the display
  - Someone with a low-DPI (or small) display due to the normal workplace being unavailable

While you could, of course, disregard all these scenarios, the sheer amount of people profiting from or requiring a character limit on lines is usually grounds for a restrictive policy regarding this topic. You might consider it silly, but as long as there is no reliable way to convert between these "styles of presentation" you will find that many people prefer to err on the safe side.
