I don't know the topography, but I'm told there are places a wall or other solid barrier may be impossible.

Now if THOSE were the dissenting property owners ... leave 'em be.

They'll learn when the solid barrier shunts ALL the traffic through their scenic paradise.

“I’m told there are places a wall or other solid barrier may be impossible”

Those would “canalized” (or “channelized”) avenues of approach. The only viable route remaining after the others are made impassable.

That’s why God made drones, intrusion detection, pre-registered aiming points, and A-10s.

Just sayin’.
