Why is this not the solution?

Better instead to make houses free and abundant.

Agreed. But SE isn't going to do that because potato.

Far from a gil sink, you're asking players to focus on nothing but money making to fully enjoy the game.

Quite the opposite. I am asking for gil to be removed from the system so that people with less gil will be able to buy more things. Without a bunch of old money tycoons who have nothing better to do with their gil inflating the market, you will not see RMT bots going for housing, because it won't be worth it to them. This means fewer people clicking the placard.

Do you honestly not understand how gil sinks work? Because you haven't given me one reason why it won't work as one. The entire reason people will pay 50M for a house is because there's too much gil flying around. Remove that gil and the price drops. That is econ 101. Inflation causes higher prices. Deflation causes lower prices. More gil being removed from the system than going into it will cause deflation. I don't know how to make this any more clear.
