Yeah, no.
There is zero indication of wizards knowingly channelling energy to make mass, and the sheer amount of energy in a single kilogram of matter comes to double digit megatons.
McCoy certainly knew fuckall about modern tectonics when he set off the New Madrid earthquakes.
None of this is true.
The White Council has not survived a thousand years by being incompetent. You just happen to see them in a bad spot, and specifically through the PoV of a character with good reason to bear a grudge and no insight into why they do the things they do.
As for Harry, as others have pointed out, from the external PoV Harry looks sketchy as shit.
So we as readers see Harry fail, we feel his pain, see every time he's a complete idiot and every time he survives due to allies, luck, etc. But most of the world doesn't.
Most of the world sees a walking powerhouse with every possibility of becoming an unstoppable nightmare.
Do I think the WC was right to kick out Harry, hell no.
Do I completely understand why they did? Absolutely.
Let's run down an incomplete list of the things Harry has done FROM THE PERSPECTIVE OF THE OUTSIDE WORLD.
As an untrained teenager he kills one of the senior Wardens of the council in a duel and flattens his home (presumably a magical fortress like Harry's place), a warden who was part of the team who took down Kemmler. He then gets off on a technicality and begins publicly declaring himself a wizard to the world.
He starts a war with the Red Court over a personal tiff (again, this if from the outside perspective) and kicks it off by killing a member of their nobility in the heart of her power and destroying her entire retinue.
He survives a duel to the death with the Warlord of the Red Court, for some unknown reason a Knight of the Cross shows up as his second. That Knight ends up death within days, brutally tortured.
He dethrones Lord Wraith and faces down Mavra in a 12 hour period.
He has support from The Blackstaff, The Hellhound, and mortal authorities.
He is seen publicly repeatedly with Laura and Thomas Wraith, the beginning of a troubling pattern.
He has killed not one, not two, but THREE Faerie queens (again this is public perception not facts).
He has called up the Senior Council and offered to take them all on, then actually SHOWED UP to back it up. In the course of doing so is aided by werewolves, a White Court hit team, and displays unexplained knowledge and power concerning the Well.
He survived and won a fight that semi-killed Luccio, and downed Morgan. Finished the fight by killing three Major league necromancer's. In addition he is aided by a Foo Dog, performs Necromancy on the very edge of legality, SHOOTS Luccio in the head, and summons the frickin Erlking.
He again survived a fight that crippled Luccio and destroyed a bastion of the White Court.
Is involved in yet another White Court affair when he intervenes in the Coup, is aided by Marcone and Einherjaren, displays hellfire and a working knowledge of Ancient Etruscan, and almost dies saving Laura Wraith.
Tortures a Ghoul to death while interrogating him in Sumerian, displaying incredible power over firemagic to do so.
He assaulted Arctis Tor, and instead of taking vengeance Mab made him her freaking Knight.
He robbed Hades and escaped alive.
He wiped the entire Red Court off the face of the Earth.
He bound Eithniu and took her eye.
He is the Warden of Demonreach prison.
He's also allies with Chicago Police and regularly is involved in bringing mortal authorities into Supernatural affairs.
He sponsored a CRIME LORD as a Freeholding Lord of the accords and has worked with him on several occasions including fighting a Denarians and Ethniu.
He is a regular ally of the Knights of the Cross and yet has also worked hand in hand with the Denarians.
Has enthralled enough Wild Fae to scare multiple top tier power houses during the Battle of Chicago.
He holds at least one of the Swords, and at one point held two.
He has been seen throwing Soulfire and Hellfire around.
He's been unable to speak basic latin but is somehow fluent in Ancient Sumerian and Etruscan.
He was shot to death. Died. And fucking came back.
He announced his return by killing TWO queens of the Sidhe on his mega darkside island during a naval battle between OUTSIDERS and the WILD HUNT.
Without insider knowledge Harry is fucking terrifying.
