I disagree that you can own things, but I certainly concede IP as a good starting point.

So you wouldn't mind if I dip my hands into the pockets of the clothing you are wearing and help myself to whatever cash bills I might find?

Also, can you wash this not-my car I'm driving, that happens to be registered in my name?

Let me know if you will be requiring compensation for not-your time and not-your effort.

You will find the needed cleaning materials at the household goods store down the street. Just walk in, grab whatever you need, and walk out.
