I built a small shed in my backyard. I didn't follow any building codes. I cooked a meal at home, I didn't follow any food safety standards. I build a gokart from scratch and ride it around my own property. Should any of these be banned? Now if I tell my friend, 'Hey, you can store stuff in my shed/grab a plate of food/take the gokart for a spin', should any of it be banned?
