Earlier quoted context omitted.
How about punishing malingering misuse of resources rather than offering a carrot. Owners incentivized to utilize land, more real estate available, foreign investment squatting suffers.
Who gets to decide what is or isn't a misuse of resources? People like you would rather use force to bend others to your worldview than actually execute on realistic solutions.
And your 'realistic solutions' leads to exploitive loopholes for people who already benefit enough without additional tax incentives, like communities that go in on luxury senior developments to meet their low-income/transient housing obligations.
