Just as people have built tall walls with overhangs to overcome these issues, it is my personal opinion that they should also make their walls thick (not necessary solid) enough so that this cannot occur.

No, it's far from from similar. There's a very big difference between using the innate skills of a spider or a horse to climb a wall, and using "gameplay sorcery" to teleport your hired NPCs inside a bannered place.

In the past, Mevans has fixed another exploit which allowed players to walk through small gaps (such as the ones left open when building with slabs) while riding small spiders. That one is a similar case to the one we are currently discussing, because they're both about gameplay mechanics bending the laws of Minecraft physics, that is, moving through solid material.
