You'd have to supplement it with a survey, to find out what how much of what should go where. I think it's a valid alternative model that accommodates a lower transaction cost and higher overall welfare - more people can benefit from consuming art - provided that the income is sufficient to motivate its production. It's certainly not an open and closed case of anarchy; that's just as ridiculous to claim. The Eurail / Interrail multi-day all-Europe train tickets have a similar mechanism. The basic requirement for travel is that you write your journey into the ticket's itinerary list (a multi-page lined space that you fill in manually); at the end, at your option, you send off the ticket to receive some kind of souvenir. Functionally this acts as a survey of which train trips were taken, so that the money from sales of the tickets can be distributed.
