You'd be surprised how much content on a wiki actually comes from anons. Some are just trolls yes, but the overall weight is that they are a productive force on any wiki. They usually don't write huge articles, but they are usually responsible for correcting the small stuff: typos etc. You should also take into account the "turnaround rate": Most wiki users start out making 2-3 anon edits, and then create an account. Forcing an anon to create an account means you could outright lose editors. Worst case scenario, you could make "patrol teams". Patrolling is work, but can also be very fun, and it keeps wikis squeaky clean.

Fun fact: On the Borderlands wiki, "anonymous editors" got "user of the month" award for "their patient and consistent watch over spelling, grammar and content"
