Roommates and alternative living situations are necessary because our housing policy is to preserve the Texan/Midwestern single-family-house lifestyles of existing homeowners. And not just to preserve them, but to keep sightlines clear of evidence that someone else might be living a different lifestyle nearby. People are not entitled to 1BRs, but they are even less entitled to streets curated for 1-2 story detached houses at trivial distances from that human epicenter.
