If you think about it, there is nothing stopping me from stealing your earwax. Apart from some distance and a few doors, of course. Overall, it would be an easy operation. All I would need is a mode of transport and few cotton buds. I would drive to your residential address and I would force entry into your dwelling. Next, I will enter your room in which you sleep within. During the next part of the operation, one of my cotton buds will enter your ear and obtain the ear wax. Once I have collected enough for my requirements, I can then leave and have successfully stolen your earwax.
