Fair; however, you do share this country with people who do not explicitly agree with all your decisions. Which is why I flagged this as a /perception/. Those still have actual consequences whether you agree with them or not.

You're ignoring national security and resistance to natural disasters. There's the part of the argument you want to have; unfortunately, it explicitly touches on several other complicated ones. Ignoring them introduces unnecessary peril to your own stated goals.
If climate change is that important then you should really be seeking to rationalize the common concerns surrounding this approach and working to address them through incorporation into your strategy. There's more than one thing to "get right" here.
