It is also mundane - everywhere you look it's the same thing. Perfection is boring; we're interesting because we're imperfect. A perfect tree would not be a circle; it would be perfect for climbing, or for building treehouses, or for birds to nest, or for fruit to grow. It is the imperfections that make a tree perfect. A triangle can be a perfect equilateral, or it can be a radical scalene, but even the perfect equilateral is not the same everywhere. Mario is a circle. A triangle can be anything from Princess Peach to Waluigi. It can never be Mario, but who would want to be Mario?
