Correction - the local system means that when the local system fails _for years on end_ then the remote part of society needs to step in to support those who are starving locally. But this is true, no matter how high you push things. If something kills all the okra (see Interstellar) then we'll have to fall back on spinach _as a society_ if we have one mega-farm. If everything on the planet dies off then we'll have to flee the solar system, or get support from neighbors in the local galactic cluster. |

What is the local vs remote system? When you have small farms local is you, and remote your neighbors who you walk to. When you have large enough farms you can generate enough surplus that the world cares - and they are generating enough that they can afford to play nice. Small farmers in general don't generate enough surplus that they can feed each other across the distance of a continent.
Support from a galactic cluster is nice in SciFi, but in reality space is too big. It is questionable if Earth/Venus could support each other, as our orbits are often too misaligned to do anything in time. (the fast trip to mars involves Venus so things are even worse). Going between stars - forget it, by the time we find out about a problem they are dead or have survived.
