There is no personal returns in managing a guild, but personal expenses. And the losses due to inattention (like the many cases that have been seen) can become quite frustrating. The guild leader has no special powers, just extra responsibilities that consume time and gold. There's a reason why only few people ever answer when calls for more guildhouses are made, and they usually do so reluctantly.
Guilds and religions are huge time and money pits, and few really want to manage them.
Most multi-realm alliances have either a religion or a guild that they coordinate at least their military movements and campaigns through. The Véinsørmoot is this at the very least. It will stay around, for sure.
