Quite often I came across questions that ask for a specific thing. More often, the answer is a simple "NO". Something like this does not exist. The dilemma here is it is difficult to prove / establish / evidence something is not there. I could be that I [person who wants to answer] does not conclusively know something like this is not there.
For example How can I hedge against local home value? Well there isn't any such product because the market is small. But then maybe some vague small company / practise somewhere offers it.
There are other such questions;
Historical day-to-day prices for all mutual funds (best if through an API)
Financial product with high variance, instead of lottery
tracking dividend payments automatically
Some similar question have been essentially answered an elaborate NO. For example;
How to determine a reasonable rate of inflation assumption for long-term care?
Are there mutual funds that invest in specific groups of companies?
Australian superannuation funds holding bitcoin?
So the question essentially is as a community how do we go about such questions. Should we leave it open or make an educated assumption / guess and say NO.
