You could force it off by disconnecting the right wires and fuses but I wouldn't do that. In addition to making your car unpassable in safety inspections in many states, you'll have a check brakes light and a voided warranty for anything related to the VSA like brakes or the ECU.
On the street, there i no reason to keep VSA off unless you're stuck in show or a situation where you need to spin the tires. If you want it off all the time because you drive like Michael Schumacher... well wheelspin isnt going to help you any because you drive a FWD family sedan.You cant throttle-steer in a FWD vehicle, best case scenario you go headfirst into a tree a little faster.
There is no reason for VSA to apply brakes unless you're already in a slip condition. Your MPG will not be affected unless you drive like a madman at which point your MPG should be fairly far down.
As for premature brake wear, that more of a descriptor of how someone drives. You can't beat physics. I someone drives "spiritedly" y are going to replace them more often than someone driving relaxed.
