It's true openness isn't free of side effects. I think a mining company that has exclusive possession over a public resource should be rewarded with the value creation (mining) and not by possession (natural resources). A government should designate the natural resources to public welfare and is ultimately achieved by openness. A resource greedy mining company would rather dispense with transparency in this case.

Regarding the borrower problem. This is a common fear of revealing one weaknesses by openness. I believe society will invent new alternatives to support the new needs. Again, it seems openness is positive overall, despite new challenges it presents.
