Numbers are key. As you mentioned, we only have estimates and examples of what's been done elsewhere in the world.
The government is there to decide, so it will choose the options that will enable it to make the best possible investments. In this context, we must, on the one hand, draw inspiration from the best in the world and encourage a partnership project between the private and public sectors; on the other hand, we must see this investment as an investment for the coming decades. It's important not to see it as a short‑term investment, but for the next 50, 60 or 75 years. We'll never have a second chance to get this project off to a good start.
