Dense is a subjective term, and solar is without a doubt a dense enough energy source.

Compare the amount of land needed to power the US with solar to the amount we use to brew a small amount of ethanol as a minor energy sourced. We can completely power the US with a fraction of the land that we currently use as a subsidy for corn farmers, who grow more corn than we can eat.

While I'm less optimistic than you on solar power, you're absolutely right about ethanol, which is easily one of the worst and most inefficient power sources we could have possibly chosen to invest in. It's a significant indictment of the US political system that so much money was shoveled into it.
I'm not sure why you are subjectively calling my number-based argument "optimistic." What do you mean by that?
Happy to discuss the numbers of your numbers-based argument, but you didn't cite your sources.
