comment How does one make sense of a delta function of a scalar field?
Well, a particular discretization $I$ is just one out of many. At the end of the day, we are supposed to somehow define an appropriate continuum limit $|I|\to \infty$.

Mathematically, the Dirac delta distribution is a more sophisticated gadget than what you say in above comments, but heuristically speaking, you're right.
