Since coordinates are purely conventional, it would be amazing
if physics "didn't work" when one chose a left-handed system.
Of course, if you don't distinguish between vectors and pseudo-
vectors (best done by using skew tensors, aka forms), you're
making a mistake that shows up when coordinate conventions are
switched on you; but it isn't the physics that's broken.
