That's good though, no? They're collecting the information from you. I know it's a joke, but it's the difference between watching my home insides without me knowing - and showing up to my home with a warrant.
The joke is made at the expense of people who are naively saying that you can't be forced to turn over something you don't have, as if that's a defense that will work. They can mandate that you collect the thing they want you to turn over, then put you in prison and seize your assets if you don't comply.
