The reason this is a bad-faith argument is made clear by the kind of statistics I quoted from the WSJ at top. We don't know with certainty how the effects of housing reform are going to fall out. But we know how the effects of the housing status quo are falling out, and it's not good for a large swath of Americans, who are excluded from opportunity already.

The existing system directs colossal subsidies at propping up the suburban development pattern and reserves most of America's residential land for single-family homes exclusively. We do this, ostensibly, based on arguments about the social value of homeownership and its importance as a wealth-building tool. And yet in the existing system, homeownership is dramatically failing a huge cross-section of Americans as a wealth-building tool.

The status quo is not neutral. The status quo is also a choice.

A similar argument extends to other issues. How many people died in traffic last year in the United States? (Answer: 40,000.) How many were injured? (Answer: 4.5 million.) How many of those killed by drivers were on foot at the time? (Answer: 6,227, the highest in three decades.)

We should treat this as an ongoing emergency. It should be the number one focus of discussions about how we design our streets and get around our cities. And yet when changes to our streets are proposed—a road diet, a protected bike lane, a roundabout—public debate tends to center around any uncertainty about the effects of the change.

What if traffic becomes more congested as a result of this? Do we have accurate projections?

What about this study I've seen suggesting that protected bike lanes aren't always safer?

There are a lot of elderly drivers in this area who might be confused by roundabouts. Sure, you have statistics about their safety benefits elsewhere, but have they been sufficiently studied here?

We should probably hold off on any change until we've eliminated all uncertainty about what the effects will be, say, invariably, those who are most comfortable with the status quo and have the least to lose from blocking change.

The status quo is not neutral. The status quo is also a choice.

The places we've built are killing us. They're also bankrupting us. A $21 billion infrastructure deficit in Illinois; $14 billion in Louisiana. Only 30% of Phoenix's streets are in good condition. And the fallout of this widespread insolvency, or soft default, isn't just going to look like tax hikes. It's going to be uglier. It might look like unresponsive 911 services. It might look like Flint, Michigan's lead-tainted water crisis, replicated in one community after another.

The status quo is not neutral. The status quo is also a choice.

Why am I delivering this litany of bad news? Because we should wake up every day and be uncomfortable with the way things are. We should not view it as acceptable. We certainly should not treat it as the presumed default in discussions of urban policies or plans that will affect what the next half-century looks like.

Yet we do. We treat the way things are right now as the default, and we allow those who are most comfortable with the way things are now to put the onus on advocates of change to defend that change, and to convince the public that it's non-threatening.

But the status quo, when it comes to zoning and what we allow to be built, is not inherently normal or divinely ordained or the result of universal revealed preferences made manifest. The status quo is the result of very deliberate policy choices. And the burden shouldn't fall exclusively on critics of those choices to prove them wrong.

Iterating Our Way to Better

Abandoning status-quo bias doesn't mean that we embrace a politics of Blow Everything Up, Ask Questions Later. On the contrary: this is one of the key reasons for Strong Towns's advocacy of incrementalism, which is often misunderstood as "be hyper-cautious and change-averse; take only the smallest and most inconsequential actions."

What we really mean is that policy change ought to look like Silicon Valley-style rapid prototyping: thousands of small, low-risk, localized experiments which are quick to implement and which we can quickly learn from and make adjustments. When we return decision-making and levers of power (and funding) to the local level, we start to make policy informed by on-the-ground struggles. We can iterate our way to a world that improves on the one we've got. And that process won't look the same everywhere.

We're going to need to learn to be comfortable with a bit of chaos, as the suburban experiment continues to fracture. It's a bit scary. But so is the way things are now. Let's stop allowing those most comfortable with the status quo, and those with the least skin in the game where its downsides are concerned, to claim the high ground of being cautious and (small-c) conservative. They haven't earned it.
