Answer:
A conclusion that is in favour:
"Using public money to maintain national landmarks is a good policy in the sense that a national landmark is a public good: no one can be excluded from enjoying the view of a national landmark like the Arch in St. Louis for example.
Because they are public goods, national landmarks are not likely to be profitable or provided by the private sector in a free market, and for this reason, government intervention in the form of public money becomes necessary".
