Yeah I think that is exaclty what is happening, the stock bushings allow for some small play so setting toe to 0 will essentially be slight toe out while driving.
In a corner you are essentially under steering the front, either slightly or a lot, only you can know that, and the front insides, of the inside wheel are scrubbing hard, also due to camber and you can end up with what you have above.
Also in a straight line, under power and under braking your front wheels open up like she wants it
if you close them up a bit in static alignment you can essentially have a 0 toe under power/braking but its hard to fully judge the effect of toe adjustment in corers as it varies greatly with the steering angle and the type of cornering you do(slow/fast).
One more thing is tire shapes, some are more rounded, some more squared off , for same size/ratio, so it will take some time to fully optimize a good alignment. there will always be a trade off
But it sux to wake up to what you posted above, good tires with destroyed insides... happened to me many times
