This is so alien to me. It's a place to live, it has walls, it has a resell value but it's not the main purpose of it. And all investments are risky by definition.

One should buy a house because one wants to save money, compared to renting, and have its own place, if you are buying for a price increase it's called speculation. If it is speculation, then you should not depend on it for your future and should put little money into it not decades of mortgage.

This is so linear to me. The idea that things keeps getting value forever is flawed and a house is too important and expensive for this kind of speculation.
