Wikipedia should be fun. Its editors should derive pleasure from the time they spend here.
Edit wars are not fun. They sap the will to edit from editors. They get ugly. They redirect energy which could be used to work productively on the encyclopedia into undoing the work of others.
Drama
Wikipedia is not Dallas. The purpose of our interaction with other editors is not to entertain bored housewives. When things get personal, productivity drops. We're here to build articles, not egos.
Enfeeblement
Editors should be able to jump in and improve the project wherever they like. Every hoop that they have to jump through unnecessarily reduces their enthusiasm and holds up improvement of the project.
