Uh… Airports? Trains? Walking? Taking the ferry?

You can literally touch four states at once at Four Corners.

Not every state border crossing is an Interstate highway having controlled access. In fact, most are not (US highways, county roads, etc.).

Most states do have no trespassing signs on the rights of ways though.

Try walking around the nation and see how much police interaction you get :)

No, no they don't. Private property does; and controlled-access highways do; but definitely not ordinary public highways.

The Illinois State Police can confirm that on August 11, 2018, Mr. David Weaver was arrested by the ISP and cited for the following offenses at the scene of a multi vehicle personal injury crash that resulted in multi vehicle fires: Criminal Trespass to Real Property, Failure to Yield to Emergency Vehicles, Stopping Parking or Standing on Roadway, and Walking Improperly on the roadway. This case remains open and ongoing in the court system, therefore we have no further comment at this time. The Illinois State Police's primary goal at the scene of a critical incident, and at all times, is the safety and well-being of all members of the public.

Indeed, it is unlawful to walk on a controlled-access highway, as was the case here (Interstate 88).

The linked article has a photo that shows many people walking on that controlled access highway, many right in the middle. Were they all arrested?

It's orthogonal to the general right to travel freely, but the story does demonstrate how overly broad procedural laws end up being selectively and inappropriately enforced to persecute under the color of law.
