Revolution is not only required but inevitable-- that's a rapid major change in the structures of our society, which needn't necessarily be acheived with violence.
Of course, the current system will unleash a great deal of violence on its way down.
But you're right, we needn't focus on tearing apart something that's inherently destroying itself. We need to BUILD the systems that will hold things together in its wake.
Like Firestorm Books has been doing, such that when the hurricane hit they got aid to some places DAYS before the floundering government structures could.
Sufficiently advanced disaster preparedness is indistinguishable from revolutionary dual power. (which is why the evil capitalist technofascists in charge right now don't want us having infrastructure, prevention, or public health etc)
