Hard disagree (says the planetary geologist).
Almost every planetary body in our solar system is the only known object in the universe that does [x], and a good chunk of the larger moons too. Some of these are probably common in a larger extrasolar framework, and we can expect to see them in many solar systems; but others may be very rare, and very precious. Consider the hemispheric dichotomy of Mars, which places its northern hemisphere kilometers below the southern half of the planet, or the equatorial ridge around Iapetus that circles it like the seam from a cheaply molded plastic toy. Consider the sulfur raining down on the surface of Europa as its orbit trails in the shadow of Io’s volcanic emissions, gently mixing water ice with potentially bioavailable nutrients from two worlds. Consider the plumes of Enceladus, the ice of Mercury, the shining salt domes of Ceres.
This is true in time as well as space; Mars had a hydrological cycle and surface weathering processes unlike anything we ever saw on Earth (which is causing all kinds of trouble trying to pick up the pieces here in the present, let me tell you); I myself participated in some research not long ago suggesting that mountains on Mars might have grown from the top up. Earth has had several major climate regimes with a radically different character, none of which exists elsewhere in the solar system. Venus almost certainly had a very different surface and atmosphere than it does today; whatever that looked like, it’s a safe bet that something unique was lost forever.
We have models of planetary formation with some granularity; within broad strokes, planets will evolve along certain pathways and within certain limits. Yes, the cosmos is ordered. But those limits are broad enough to encompass literally everything you have ever experienced, and we have not begun to exhaust even the simpler possibilities of worlds that are barren of life. Other systems with other worlds will do things we never imagined, and probably never will imagine without first going to see what the universe has to offer.
In a sufficiently vast universe, all of these will come again. But then, in a sufficiently vast universe, so will you. Below that threshold, these things really are incredibly interesting.
