oki this from the PHB about the weave, the full explination... i ask you both to look at the second part, where it says Mortals cant... to sum it up, no weave, no spell, period !... The only referens i know breaks this is runelords, and they existed before the weave, the second is making your self more or less a god...

The worlds within the D&D multiverse are magical places. All existence is suffused with magical power, and potential energy lies untapped in every rock, stream, and living creature, and even in the air itself. Raw magic is the stuff of creation, the mute and mindless will of existence, permeating every bit of matter and present in every manifestation of energy throughout the multiverse.
Mortals can’t directly shape this raw magic. Instead, they make use of a fabric of magic, a kind of interface between the will of a spellcaster and the stuff of raw magic. The spellcasters of the Forgotten Realms call it the Weave and recognize its essence as the goddess Mystra, but casters have varied ways of naming and visualizing this interface. By any name, without the Weave, raw magic is locked away and inaccessible;the most powerful archmage can't light a candle with magic in an area where the Weave has been torn. But surrounded by the Weave, a spellcaster can shape lightning to blast foes, transport hundreds of miles in the blink of an eye, or even reverse death itself.
All magic depends on the Weave, though different kinds of magic access it in a variety of ways. The spells of wizards, warlocks, sorcerers, and bards are commonly called arcane magic. These spells rely on an understanding— learned or intuitive— of the workings of the Weave. The caster plucks directly at the strands of the Weave to create the desired effect. Eldritch knights and arcane tricksters also use arcane magic.
The spells of clerics, druids, paladins, and rangers are called divine magic. These spellcasters’ access to the Weave is mediated by divine power— gods, the divine forces of nature, or the sacred weight of a paladin’s oath. Whenever a magic effect is created, the threads of the Weave intertwine, twist, and fold to make the effect possible. When characters use divination spells such as detect magic or identify, they glimpse the Weave. A spell such as dispel magic smooths the Weave. Spells such as antimagic field rearrange the Weave so that magic flows around, rather than through, the area affected by the spell. And in places where the Weave is damaged or torn, magic works in unpredictable ways— or not at all."
So no sorcs isnt a exception, they still need to use the weave as a "interface"... Heck even devine casters isnt even excempt...
a sorcerer is
"Arcane magic is in your blood, as a touch of either ancient draconic power or untamed chaos energy, and you unleash it through sheer force of will and physical discipline."
