Problem I see is any advancement that makes violent self defense easier for the individual has the flip effect of making aggressor violence easier for the group of individuals.
In my mind,that reality always ends in a gov't or multiple competing gov'ts in the end.Which is what we have today,which makes sense since nature is essentially ancap and we came from it
Issue I have with ancap is as soon as value is created and someone else wants it, it can become economically viable to steal through violence. Not everyone can defend themselves equally.
To a degree it's reactive, if burning come coal caused instant death, we'd immediately stop.If however it causes some issues over a longer time frame, we choose to react to more immediate issues
Environmental awareness comes with wealth. We worry about it because we can afford to. Bring economic freedom to the rest of the world and they'll be able to afford to worry too.
