Isnt a moat and a wall pretty similar in function? They both keep people in or out of an area.

Also werent all "moats" commonly paired with a wall in real life? As in a moat around a castle wall?

[grey-area]

In a castle for defence, yes similar in function but not form and often used together not one or the other.

In business metaphors no they are used for different things and also when you create a metaphor you should stick with it, that’s what makes this jarring and weird.
