By that logic it's apparent that D'hara does not care for managing her cities.
Just because a guild house or two has gone into disrepair doesn't mean that people don't care about the guild. Also, as far as I know, the alliance and guild go hand in hand.
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.
