A state community services department keeps a Community Participation Roster that lists residents who attend public volunteer trainings, join neighborhood-safety briefings, or serve in outreach programs. The roster is kept by state agency staff and may be reviewed by program directors. David, a resident who appears on the roster, files suit in federal court against the responsible state officials, seeking an injunction to stop the practice. David alleges that because nearly every active volunteer appears on the roster, the file is likely to chill his First Amendment rights of speech and association. David has never been denied any benefit, disciplined, or threatened with adverse action because of the roster. What is the clearest reason for dismissing David's suit?
