There's the argument that if you build a 20-foot wall, they'll bring a 21-foot ladder. That's why many borders in nations around the world use parallel walls a few yards (meters) apart.
Would-be violators land in the 'ditch' formed by the two walls, are seen on camera, IR, heat sensing, etc, and are in for the race of their lives to get that ladder through barbed wire barriers, past a few German Shepherds, up against the next wall and over before being apprehended.
The cost is much less than building a freeway which are about 12 - 24 inches thick, poured on a bed of asphalt over compacted, lime-treated soil. Tilt-walls are only about 4 to 8 inches thick and require much cheaper concrete.
We have millions of miles of local, state and federal (interstate) roads. Building 2,000 miles of parallel walls would be fractional by comparison.
