Yes, but "a" as in one isn't going to help much unless it is really targeted at funding works that could blow up in some sense, including funding marketing of them. (Kinda related, imagine a "free culture ~netflix" ... subscription $ used to really nicely package/stream free video, and if enough $, start funding new video, which'd have a built-in audience. A recent idea of way too many I'm kicking around.) Generally mandating output of public/publicly interested cultural funding be freely licensed is a next frontier for policy (cf OA, OER, PSI mandates).
