What confuses people is that other things have real value. You can actually eat an apple. You can drive a car. So, they expect cryptos to have such a basis for their value.
Except that currencies, in general (not only cryptos), don't have such a root value. To explain that to people, I usually use the $ Dollar example. I ask them where does the dollar get its value. Suddenly, they realize that not every thing needs a root value.
