Heh.. the tacit presumption that "causality" is straightforward.

Volumes have been written on that glimmer of an idea - 'causality'. I tend to lump it with, "action at a distance", in ~~ philosophical 'class'.
(Spin of electrons separated at t=0, now an entire "finite but unbounded" cosmos away? Is spin conserved?? and the like.)

I do not think that word causality gets the scrutiny it deserves, in very many "obvious conclusions" we casually toss off (especially of the either/or kind).



But then, if it were all easy -
Maybe even Econ would work (for relaxed meanings of 'work')
