Right,  You're certainly old school :-)

Of course, there serves no justice to summarize history in just a msg or
two. Yes, much of it was due to punch cards mentality, after all, teletypes,
terminals was just a emulation of the punch cards and when programming
"jobs" it wasn't imaginable to want to "word wrap" into the next cards,
although it was possible by punching a hole in column 6  for FORTRAN people
:-)

While "GUI" has allowed for widening widths at the user level, as you say,
its still all dependent on backend, legacy and/or heterogeneous transports
and storage concepts. :-)

BTW, we were using Fidonet to transfer mail/files between mixed storage
systems.  I get the limits the fidonet packets had off hand, but I'm pretty
sure it was <80.  Don't remember.  But doing the gates, I recall there were
a few mail hosting systems who used 28-30 to maybe 50-72 characters fields
and much of it because part of line display was taken up by the field
description any/or prompts.

For example:

From: [....]   Date: [...]
To:   [...]    Flags
Subject: [......]

So it was a battle of ergonomics, esthetics, pareto's principle (80/20 rule)
to get the most of what you can on one page without over doing it.

When internetworking came around, I recall the mental battles such as:

Enter your email address: [.... remaining width of screen-2.....]

That only leaves 50-52 clean one line inputs :-)

Of course, we evolved and used two lines to get a little more:

Enter your email address below:
[.... width of screen .....]
