FFS if you want to stick on the toothbrush thing you are (what actually seems intentional) being obtuse about it.

Stuff like a toothbrush you wouldn't have to share around or whatever you are thinking. If it's a needed or benifcial for society, you would most likely have funds or resources given to you in either the form of a toothbrush or money to buy a certain minimum standard of tooth brush.

No idea why you have to make insane leaps to things like people stealing your personal belongings.
