'Any costs' are not the same thing as the example descriptors. Examples of that sort are not generally viewed as exclusive. Under RNT, a nation seeking free things also would not interpret them to be exclusive, and it would be likely that such a view would win out in the end.
So what would you prefer then? Something like "all"?
[I agree with Uan aa Boa's point about there needing to be incentives-I think this is the best possible idea for them unless you have some other incentive scheme idea. So I'm curious what language you would prefer.]
