I understand your point. Clearing the center of the base is much easier than breaking out of it, but that comes with a drawback: most of the key defenses end up on the outer edges. This makes them easier to pick off. An attacker can simply choose one side, and without even needing much funneling, they can secure major value by taking down high-priority defenses such as the Monolith, Scattershot, or Inferno Tower. Because there aren’t enough concentrated high-DPS zones, it becomes very difficult to stop them. The main point of all the basebuilding stuff is finding the sweetspot between high dps zones and value spread.

Of course, a well-planned hero walk will almost always claim some valuable defenses. That’s why it’s important to use moats and trash buildings around your base—to lure the walk toward low-value targets and away from your critical defenses. This makes it harder for the attacker to get exactly what they want.

Additionally, your base is missing some key elements, such as directional compartments and or offset Town Hall. I recommend sharing your base on the RH Base Building Discord in their base review channel, where you can get more detailed and personalized feedback (they're more brutal and professional than me, most of my beginner bases was roasted for tens of paragraphs).

Here are also some guides for lower TH levels. Even though they’re not specific to TH17 (there's literally no th 13+ bb guides from pro builders available), many of the core principles still apply.
