This ignores the Player's Handbook. pg 202:
"The target of a spell must be within the spell's range.
For a spell like magic missile, the target is a creature.
For a spell like fireball, the target is the point in space
where the ball of fire erupts.
Most spells have ranges expressed in feet. Some
spells can target only a creature (including you) that you
touch. Other spells, such as the shield spell, affect only
you. These spells have a range of self.

Spells that create cones or lines of effect that originate
from you also have a range of self, indicating that the
origin point of the spell's effect must be you (see "Areas
of Effect" later in the this chapter).
Once a spell is cast, its effects aren't limited by its
range, unless the spell's description says otherwise.
"

The Range on Spirit Guardians is "Self", the only target can be the cleric. A spell with a Range of self, can only affect the caster, but that does not mean that others may not suffer from the effects of the spell.

The conclusion that you reach is only attainable if you ignore the italicized sentences. A conclusion reached while ignoring critical information is by definition an incomplete conclusion.

Which is why, I reject it.

Dispel Magic is a horribly written spell, hopefully future versions are better. Spell Descriptions as a whole need to be modernized, and made clearer.
