There's an older version of this principle used to compensate authors for library borrowing in the UK and other countries called Public Lending Right. The government puts some tax money into a pot, and it's paid out to authors in proportion to the number of loans of their books. There's also a cap to stop the bulk of the money going to a handful of bestselling authors. In some ways, this can be seen as croudsourcing decisions on government subsidy, which is an interesting model.
