Can someone please tell me how you would explain "content coins" to friends at dinner who don't care about crypto?

Can anyone simplify this?

"you know that watch, purse, car, sofa, tv, you bought? well imagine if you needed your receipt to return it. The only way for you to prove that you bought it was that receipt. Don't you buy things because you like, and want, to own? Well imagine if you could buy the content you like/want. 

Yeah, don't think too much more than a coin represents a receipt of something you bought"

(i love thinking about these types of questions aloud)
