Like, for example, its 5 moons including the biggest moon relative to its Planet/Dwarf planet, its irregular orbit, its Dwarf planet classification, and just its sheer distance wouldn’t be there anymore; of course it’d be less interesting there instead.

To be fair, removing it from its existence in the Kuiper Belt to instead *just* be another average moon of a planet with 95 of them already removes most of the things that make Pluto interesting entirely.
