Stop being so bloody dramatic. God forbid you actually have to save up and get something past release day. My FC thought we were doing good with 10 million gil and now we have to pay 100million, disappointing yes, but you know what, its not the end of the damn world. Continue saving and you'll eventually get a house. SE said instances can fill up, but they also said more instances can/will be added as needed. Housing is intended as a long term investment, in a game where everything is instant gratification its something that was badly needed.

Edit: Yes, I agree, prices on Legacy servers are insane and stupid. In this case however, 10 million is not the dream crush OP is making it out to be. I'd be more upset about the 625 million price tags.
