> It has killed every government that even dared to discuss it. And politically it is utterly impossible to defend

Then pull it out of political discussion! We don't have political discussion about "how to hang people of color Q better" anywhere in the world (mostly) anymore because we've wrote it in the text of our f laws that violence and racial discrimination are forbidden! Not on the political menu anymore.

Same needs to happen with lots of stuff concerning climate, ecology, sustainability etc. - we need to restrict the political menu to only the right choices.

And use the states' monopoly on violence to enforce these choices.
