What's up with this universal law and personal gain?

I use my abilities for personal gain all the time. Since I don't see everyone exclusively caring for others, I suspect that almost everyone does.

Am I to assume that if you are a subsistence farmer and you use your ability to talk to your crops to make them grow strong and provide lots of food, it will only work if you don't intend to eat any of them?

This just strikes me a self imposed limitation because of not feeling worthy. Of course I could be wrong, so I am asking.
