Oh goodness, this. I'm probably influenced by my Wikimedia past as well. Anon vandalism can often be dealt with through use of vandal prevention extensions (i.e. AbuseFilter) and things like small rangeblocks if the IPs are close to each other (I managed to squelch out severe vandalism on a wiki I admin by instituting a rangeblock once). Limiting anonymous editing in the interest of collaboration forces an assumption that anons cannot be collaborative, IMO. Especially when considering the reasons for not creating an account you've listed. I guess I could see it being useful for certain communities, but I can't see myself using it where there isn't a reason Wikia staff would want IP editors blocked (i.e. COPPA). I think it would be much more useful (presuming it's not an implementation nightmare) to allow admins to enable/disable certain useful wiki extensions (Abuse Filter, Gadgets, stuff like that) than to give them a button to limit editing in the interest of forcing a sense of collaboration, especially if they're anything like I was the first time I edited a wiki (and I'm sure those types of users even exist in admin positions, considering the learning curve to wiki editing even here and the relative ease there is in making a wiki). It just makes the wiki feel more closed to me, not a collaborative site that ANYONE (who does not have a good reason to not be there) can edit.

Granted this doesn't apply to the communities I currently admin, as Wikia would want them disabled for COPPA reasons.
