We need Zero Knowledge proofs for renting apartments and getting mortgages. It’s such an insanely invasive process. I’ve had people ask for six months of bank statements and tax returns in apartment applications. 

I should just be able to generate a probably true hash that says “yes I can afford it and I’ve never missed a rent payment in 20 years” without exposing so much personal information

100%, this is feasible but likely the barrier is the perception of the verifier - they have to grasp a minimum of cryptography to actually be willing to renounce seeing hard evidence.
