In that you don't know what you may turn out to need to install later,
or how big that's going to be. I know of some *programs* which are
multiple gigabytes in size (though to be fair, they're all A: for
Windows or Mac, B: games, or C: both), and I'd hate to discover the need
to install them and not have enough capacity to do so.

ISTR having also once run out of space on / because of filling up /usr
(etc.) due to installed packages, again on a previous machine, and I
*definitely* don't want to risk doing *that* again.

Whereas I'm more the pack-rat type. Even excluding the redundant copies
that I haven't properly unified from various past system-migration and
data-recovery scenarios, I have multiple TB of total data, some of it
decades old and irreplaceable.

Though the large majority of that isn't installed-system, it's
user-data, i.e. (quite properly) stored under /home.
