If you're gardening in my yard

If you're gardening in my yard, I would be within my right to stop your "labor" because of your aggression onto my scarce resources.

Scarcity is where the need for private property arises! For things that need not be scarce, there need not be ownership. If all it took was a little labor to arrange non-scarce goods (& patterns) into scarce goods (& patterns), who are you to tell someone they can't do it?
