New walls are not easier to destroy, they simply do not splash. This was to counter a strategy that raiders employed of building a wall off-claim, destroying it, and having it then splash and destroy on-claim walls. They would be able to get through a layer or two of walls almost for free that way. The fact that you can also destroy a wall that you put in the wrong place without consequences so long as you do it quickly is a nice bonus, but not the point of the mechanic.
