>it was the inability to remove debris form it's orbit.
That's not what "clearing the neighborhood" means. Jupiter is still a planet even though the asteroid belt exists and it has rings and moons.
To be a planet, a body has to be massive enough that its gravity has "cleared" all of the mass in its orbit, either by ejecting it, capturing it into an orbital resonance (as with Neptune and Pluto), or capturing it directly as a satellite. Pluto fails to meet this criteria because it is dominated by Neptune and has little gravitational influence on the many objects like it in the Kuiper Belt (which are also dominated by Neptune, as the asteroid belt is dominated by Jupiter).
>Even Earth's orbit is littered with shit, some bigger than our fucking moon that we pass by every year
I'm not sure how big you think the Moon, is but every single asteroid in the asteroid belt combined combined amounts to less than 5% of the mass of the Moon. The Moon is something like the 12th or 13th largest object in the Solar System period, there are not random planetary-mass objects just flying around out there.
There are tens of thousands of asteroids and other small bodies in the inner Solar System, but they have gone billions of years without falling into the Earth or the Sun and are unlikely to change that anytime soon.
