A public good is a good that is both non-rivalrous and non-excludable. Establishing a federal monopoly doesn’t turn the product of that monopoly into a public good. Likewise, a public good can be provided by a non-government entity.
Jokes aside, I getting hung up on that term in this context feels unnecessary, it was quiet clear what kaitai was talking about from the text he wrote.
It’s disingenuous to confuse the meaning of the term “public good” in order to justify government monopolies. Everybody knows that part of the role of the government is to provide “public goods”, but that’s based on how the term “public good” is defined, so it’s dishonest to use that to justify establishing a government monopoly over a non-public good.
