Why are Village Idiots allowed to choose themselves

It seems like this is a free Vortox check that should not be allowed. The Dreamer is not allowed to choose themselves for this reason, so it's weird that Village Idiot doesn't have this restriction.(Even the drunk VI must get false info in a Vortox game, so getting a "Good" on yourself instantly disproves Vortox regardless of whether you're the drunk one)
