State-level funding sounds good on paper but would work poorly in practice because the federal government benefits from its sovereignty in ways that state governments don't. The vast majority of Americans' tax revenue goes to the federal government, not to state or local governments, even in wealthy, high-tax states like California. And state governments, unlike the federal government, don't have access to effectively unlimited borrowing capacity at <2% interest. Also, California can't shut down its border to Floridians - or prevent Californians from traveling to Florida and then returning - to stop the virus from being carried from Florida to California.
