Maybe instead of saying, "you're not a fraud" to each other, we should say, "Yes you are! A con artist extraordinaire! In fact, you are pulling off the steal of the century by creating this completely made up THING and showing that it has value in an incredibly convincing way! You are making a Made Up Thing, Fantasy Whatever, In Your Head, Into Something That Will Look Like People Living Their Lives In A Room! or On Top of a Mountain! or in a desert or outer space or under the sea! If you keep at it, it will make people have weird dreams and maybe even make them choose specific real-life actions! They may even trade hard-earned dollars as a result of it, and as we all know, nothing makes anything more real than money! Go forth, young shyster, you liar, cheat and bullshit artist, and manufacture mass delusions!"
