Because a pencil or especially a ballpoint pen would probably leave an
indentation, and if all your cards have those indentations they won't
stack right in the card reader?

I'm guessing.  I've never seen punch cards in actual use except as a
visual aid in a computer history class.

Probably because there was physically no other way to get the case open,
but again I'm guessing.  I *have* used a Mac Plus, but I didn't own it
and so was never in a position to upgrade it.
