A planet is a celestial body that
(a) is in orbit around the Sun,
(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and
(c) has cleared the neighbourhood around its orbit.
I understand your point but the defination as posted above taken from the IAU site doesn't state has cleared most of the objects in its orbit it says simply has cleared the neighbourhood around its orbit. They should change it to say cleared the orbit of significant objects this the only point that disqualifies Pluto as a planet so to disqualify Pluto this needs to be amended. Going by this one point as written there would be a lot less planets in our solar system.
