That isn't the issues here. The issue
is instructor judgment. [...]
Making a case for allowing a 2 hour student to taxi an airplane unsupervised
is something you might want to revisit.

Well, all we know about the pilot is that he is a "two hour student",
which doesn't say much. The same argument you made could be made for
IFR flight - allowing a ten hour student to fly an airplane all by
himself, through the air, and a hundred miles an hour, even though he is
not ready to fly in instrument conditions. The issue =there= is also
instructor judgement. However, the lack of instrument experience has no
bearing if the student is not going to fly on instruments. Likewise,
the (presumed) lack of ability to fly through the air safely and land
gently has no bearing if the student is only going to taxi at ten knots
with a nosewheel.

Instructor judgement would include this.
