Not this again....
Right:
- you will use it one week to a month perhaps
- you will get bored of it / why? Because why go stand idling in a room without anyone there or hardly anyone? Even in a guild that has 500 members
1. will you be there with people you actually LIKE of those 500?
2. why would people be there in that ONE spot when they can walk/fly/run around in a city or..... the open world?
- oh you will have an anvil and other profession requirements available in there? Really? So I have to go into an instanced room with a loading screen to get to my NPC's? While I can just fly to the locations I need in a city? Or if it is PHASED, it would become a hotspot and probably very lagsensitive.
Look from a ROLEPLAY POV I can understand. Not from any convenience POV. It is a waste of resources. There are a zillion other things in WoW that needs attention before this.

Let us say that one can built a house wherever the player desires.
1. annoying rich guild A that know where rival guild B will be making a house, will just get a bogus guild and set that house right at that very spot.
2. you could get wildgrowth of houses where one does not want it - could be made so by blizzard that there are a FINITE available spots on a server and locations
You claim that people will go out and about when you have houses everywhere. Really? So let us assume the most logical scenario > your Hearthstone is bonded with your guilds house. = no one sees the world, your house is where you could go idle. Or even worse: Blizzard makes them cloaks a way to portal to your guildhouse. Which will probably not be used very often since your guildhouse will not be next to the center of the expansion where the shit is going down.
Ultimately it is a waste.
