You're asking me to think more deeply than I had time to in producing this. I can see an argument for many things. Again, I used nuclear energy as an example, but even building a dam blocks a river. You're looking at a 30- to 50-year project lifespan, and there is a good argument for that.
Now, I put five years in because I thought that was pretty safe to cover almost every significant piece of legislation, but many of them have much longer-term implications than that. However, I again emphasize the point that the farther you look into the future, the dimmer and dustier it is.
