Subject: Re: Also in his own words
Money is fungible with respect to a single party controlling his or her income or within a business attempting to make decisions with its cash on hand.

Still doesn't affect the point. Imagine the government offers me a subsidy to purchase EV's in the form of a tax credit of $1,000 - letting me keep $1,000 of my own money that would otherwise be paid in taxes if I buy a new EV. Now imagine that they switch from a tax credit to a direct payment - if I buy an EV they send me a $1,000 check. My purchasing decisions are exactly the same (barring some minor timing and friction points) - I'm indifferent between whether my subsidy takes the form of a $1,000 reduction in my taxes if I buy the EV or a $1,000 payment if I buy the EV.

It's still a subsidy. It has the same effect.
