Yoshi said openly that they don't have the server capacity to support every FC that wants a house, and that they won't be able to add that server capacity in the near future.

Everything else is an excuse. The "trick" is getting you to focus on issues like entitlement, price disparity across servers, and gil generation. The truth is that the feature wasn't ready, and Yoshi is banking on most people's reading comprehension being too poor to understand that.
