similarly, the top rung of a ladder would bear all the stress--maybe more than it could handle. Do 30 foot ladders currently exist? I haven't seen one. If they solved that problem, they're faced with impaling themselves as they scale the spikes, then they've got a 30 foot fall.

It's beatable, but not by many. It would drop crossers to a trickle.

32 feet is a standard ladder size. In this situation you would just strap a wooden slat across the top of the ladder before you raised it. Then it would be supported on two poles.

And yes you can even get 48 foot and 60 foot ladders. But they cost a chunk of money.

And solve the “ Roberts ruling “ of no matter where they cross as this would be a major detterent and also I’m assuming have a legal entry point armed and guarded

A thirty foot high wall would require TWO 38 foot, not 30 foot, ladders.

You have to allow for the lean in the ladder and have another one to climb down the other side.
