Let's say you have to use everything in your own house so you can't sell stuff to make money. Would you just walk into Coles or IGA or Costco and load up your cart full of stuff and just walk out, if you knew you could get away with it 100% of the time with zero legal, moral, societal, or any kind of repercussions other than living with your own conscience. So you're still stealing, you're harming their bottom line or causing them to pay more insurance. The magic makes it so no one else ever know the stuff was stolen.
Or would you just do it to big billion dollar chains and never to independent places or co-ops or whatever.
Now I know why you had to open Christmas presents early..
