cherrybim: You misunderstood my argument.
You thought I meant that we should not pragmatic concerns into account when determining halacha. That is of course incorrect, the halacha is full of examples where we are meikel for poor people, and where things are permitted to save a life, or for sick people to feel more comfortable.
I actually meant, that once we determine halacha including taking all the considerations into account that we can then rest assured that Hashem will not “punish” us for keeping his Torah, and will arrange the world in the way that is for our best.
I presume you do not disagree with that. But if you do, tell us about it.
