Mark July 3, 2013, as the day Big Government finally imploded.

July 3 was the quiet afternoon that a deputy assistant Treasury secretary for tax policy announced in a blog post that the Affordable Care Act's employer mandate would be delayed one year. Something about the "complexity of the requirements." The Fourth's fireworks couldn't hold a candle to the sound of the U.S. government finally hitting the wall.

Since at least 1789, America's conservatives and liberals have argued about the proper role of government. Home library shelves across the land splinter and creak beneath the weight of books arguing the case for individual liberty or for government-led social justice. World Wrestling smackdowns are nothing compared with Hayek vs. Rawls.

Maybe we have been listening to the wrong experts. Philosophers and pundits aren't going to tell us anything new about government. The one-year rollover of ObamaCare because of its "complexity" suggests it's time to call in the physicists, the people who study black holes and death stars. That's what the federal government looks like after expanding ever outward for the past 224 years.

Even if you are a liberal and support the goals of the Affordable Care Act, there has to be an emerging sense that maybe the law's theorists missed a signal from life outside the castle walls. While they troweled brick after brick into a 2,000-page law, the rest of the world was reshaping itself into smaller, more nimble units whose defining metaphor is the 140-character Twitter message.
