I am in support of any measures to make the lives of speculators and investors miserable but even the graphic you share endorses increasing housing supply! Singapore is famously super YIMBY and builds tons of public and market housing.

Frankly, whatever else we do, there is NO solution without significantly more supply. Yes, let’s change our tax code to stamp out speculation, but it will take years, if not decades, to catch up on building enough supply even if we make changes now.
