Would this be a case where the expectation value of whatever physical quantity you are measuring is the same every time you measure it?

Yea - its called the Dirac Delta function. And it is remains in that state - yes - it will always give that position.

Would this be a case where the expectation value of whatever physical quantity you are measuring is the same every time you measure it?

Thanks

In principle when starting with an L² Hilbert space a singularity is no problem as long as the wave function remains square integrable. But we are doing physics, not mathematics, so the question is whether there is a physical system where such a behavior makes sense.
