Please point to where I suggested that it's not possible to want or have both. The operative word in my comment is "to focus on".

I don’t think that is helpful though. Some people focus on this, others focus on that, and we can all both cut down our journeys while also packing lighter when we do travel. We’re not going to solve this by ‘focusing on’ any one thing. I’m really tired of criticisms of perfectly good work that amount to ‘but this other thing is more important’. There’s almost always something else more important. So what?
