Well, those people doing all those amazing things inside their instances could instead be actually doing them in the game world. After all, it's supposed to be a massively multiplayer game, not a series of instances where people hang out in their own private lobbies.

It might take people out of the game, yes, the same way instanced personal housing will. It's not like FCs will spend DAY there (unless they're really inactive <<), but it'll be a good place to convene before an FC event, meet up to trade things between your members, put stuff in the bank, craft something for the FC, or just stare at whatever cool decorations that FCs are allowed to have.

Really, I think that having an actual building creates a foundation (literally) for an FC. Otherwise it'll seem like nothing more than a communication tool, such as LSs. With a building, you have the ability to offer FCs more creative options, such as level and abilities, banks, and such. You could do the same without a building, yes, but it'd all be controlled through some NPC in the middle of town, which would seem... less impressive, somehow.
There's also something called non-instanced housing too.
