EMAS is an expense to the airport or the city/authority. A hull loss doesn't cost them anything - that is a cost to the airline or its insurer or the leasing co., or whoever.
Different pots of money controlled by different people and entirely separate budgets.
Unless airlines want to pay for their own EMAS installations at difficult airports they serve. Or threaten to stop service unless the airport pays for EMAS. Or lobby the FAA or equivalent regulators to lean on the airports to do it.
