Housing does not exist to tie players to the game. It exists because it is a popular feature in MMOs and players always request it when it is absent. Happy players with things to do are what keep them tied to a game, not ownership of a house in a game they otherwise have no interest in playing. Only fools pay to retain ownership of virtual pixels in a game they aren't playing instead of spending that money on the game they are playing.
Are you being serious here? Because if so you really are making a weak argument; especially if your such a big fan of proving it.

As for 7.0 if the trend continues we will see a new housing district; to claim SE is not taking action to address the need for more housing or will suddenly stop doing so given that they have taken steps is acting in bad faith at best. But hey if your around when 7.0 is announced I look forward to your apology for doubting :-P.

Also to address your arguement about Demo - we are talking about the current issue; not the past.
