It's all political for you, isn't it?
You make a lot of political arguments there but they don't do anything to counter the actual science of climate change. Understand the science first then it's possible to have a reasonable discussion about the political implications. If you think global warming is just contrived science to push a political agenda then it's probably impossible to reason with you.
Earth has no optimal temperature. But human civilization probably does have an optimal temperature range as all of our infrastructure is built around what it has been in the past couple hundred years and it's going to be very expensive (in both money and probably lives) to adapt to a new higher temperature.
