This is written in such a way that it seems like it makes sense, but it ultimately takes its conclusion as an axiom and is thus essentially meaningless.

Gerrymandering is to draw districts according to political party affiliations. So of course if you only divide up your districts by political party affiliation (in rather extreme ways) you will discover that doing so doesn't lead to stable political systems. No shit, that's the problem with gerrymandering.

Any serious analysis of this problem needs to confront the realities of geographical location and migration.
