The author, an economist, proposes requiring cash for all gambling transactions, arguing that pulling out physical hundred-dollar bills creates friction and visibility that apps and cards eliminate. He notes roughly 20 million Americans are estimated problem gamblers, about 6% of the population, and that prediction markets bypass state protections like age limits and in-person requirements.
He is candid that outright prohibition is a dead letter: states are hooked on gambling tax revenue, media outlets on gambling ad dollars, and leagues on the engagement gambling drives.
