The people outside the town who buy houses here either expect to rent them expensively, or to use them as an investment because they expect the costs of housing to grow. (Or a combination of both.)
Refusing to build more houses means doing exactly the thing they want—it keeps the rents high, and it keeps the costs growing.
If you have 500 000 people in the town, and 100 000 houses are owned by people outside the town, you should build more houses until there are 600 000 of them (i.e. not only 500 000). Then the people outside the town will find it difficult to rent their houses expensively, and may start worrying that the costs will not grow sufficiently to justify their investments.
I agree that something being “natural” doesn’t make it “right”. But “natural” is still a force of nature that you have to include in your predictions… unless you are okay with getting your predictions systematically wrong.
Applying this to the examples you mentioned:
Yes, 100% agree. Notice that this doesn’t say anything about aggression being good or otherwise desirable; the statement is positive, not normative.
Do you have an alternative explanation for gender ratios in violent crime statistics?
Okay, we have a “should” here; that is a mistake. But we could make a positive statement out of it, something like “on average, females will be more successful caregivers than males”, especially if they are randomly selected from the population (rather than self-selected).
Of course, “more successful” does not automatically translate to “should”; we need to balance it against other interests.
Here, I would make a statement like “human social hierarchies are a natural attractor, so if you want to avoid them, you need to think really carefully about how to design your group, because it is very unlikely to happen automatically”.
Similarly, something like “there are many dominant men, so you either need to accept that you will have a leader like this (and maybe focus on figuring out how to choose the best one out of multiple candidates) or you need to think really carefully about how to avoid this outcome”.
The positive statement would be something like: “you need to think really carefully about designing a vegetarian diet that will be healthy in long term, because the most likely outcome of ‘just don’t eat meat, duh’ is some kind of nutritional deficiency”.
Metaphorically speaking, opposing the nature is like opposing gravity. Yes, you can build airplanes and tall buildings. But you need to design them carefully, otherwise a disaster will happen. Just saying “I hate gravity, it is such an oppressive concept that it should not be allowed to mention in a polite society” is not going to do it.
