I don't have a down button, but I can see why someone used theirs.
1. Why would you verify local need, if the need is national?
2. Why would you verify inability to pay with ability to pay?
Spain's demographic problems are exacerbated by lack of rail access to certain areas. Portugal faces similar issues. If they want a strategic rail line, why would they apply the unrelated criteria you propose?
I know it's not you, but even if you had downvote rights you wouldn't be able to revenge downvote a direct comment.
If it's not profitable nationally then I argue the need isn't very big, so they should spend their tax money more wisely on things where the need is clear. Local municipalities are well aware of their needs hence why it is better to have it local.
I don't get your two questions, maybe you can rephrase them?
By that logic, a country can't make long-term investments, and can't provide unprofitable services that have other benefits. My two questions challenged your circular reasoning.
