your questions regarding the game rules (improving the interpretation).

I believe that a player should have the ability to attack a Guard Tower from any cell without restrictions, using any route. If the rules don't allow for this, it needs to be clarified.

I just phrased it from the perspective of prohibiting such an action.
In general, we need to start with the fact that there is a controversial situation and we need to decide what to do with it in the future – prohibit it or allow it, and then formulate the wording.
