Not everyone has the same problems to solve. Morality will be trumped by needs. Not many people will pass up food when they are starving, or medicine they need to live if they are dying. No one should confuse how things are now with after shtf.
If one of your children will die for lack of medicine and you cannot buy it now in a quantity sufficient to last more than a month. A medicine you can’t concoct yourself. It is stored in large quantity locally but you can’t buy it. Should you let your child die or should you take what you need from the pharmaceutical supply? I know what I would do without hesitation.
