Yeah, this kind of realization can be surprisingly empowering, because it takes something that seemed like unavoidable natural law and reveals it as an adversarial relationship.

To offer a boring but lower-tech version: Shopping centers which are deliberately designed to make people enter/exit through stores, and the companies that pay to rent that space in particular. So there's nothing awkward about tracking in some water on a rainy day, the company chose that tradeoff.

Yes, exactly! We generally treat spaces with the benefit of the doubt, which I think is smart for mental health. A conference center which doesn't have the bathrooms close to where you'd expect probably is just badly designed rather than actively trying to mess with you. But this breaks down for certain spaces: shopping malls, airports, etc.
