Nice subreddit, I agree with a lot of what you write. In particular I wish more people were looser, as you seem to be, with the assumption that actors within an economy act rationally. It's impossible to act rationally given the huge amount of information asymmetry in the economy, and especially given that others' information asymmetry will cause the economy to not behave rationally regardless of whether you can make rational decisions on it.

It's also impossible to rationally determine whether an arbitrary law / policy change will pass at arbitrary point in the future. So with housing, because we aren't guaranteed that interest rates/zoning/taxes will behave predictably, we can't really rationally determine a "true" price for a house in a market where those may change
