This is how GFCI breakers work -- they watch for current "leaking"

No they don't. They look for imbalanced current flow between the two

How are you going to get the imbalance without some current finding
another path to the neutral conductor, which is bonded to the grounding
system at the main panel? You two are describing the same thing, from
different directions.
