The real problem isn't even gerrymandering, it's having a district system at all. Gerrymandering is merely one of the symptoms of a district system.
Having a district system will tend to reduce the number of viable parties to two. The article doesn't even question the fact that there's only a blue and a violet party in the example. In reality, lots of people feel badly represented by even the best of those two parties. For as long as I've talked to Americans about politics, they've complained about voting for the lesser evil. Why not vote for a party you actually agree with? Because it's not viable in a two-party system.
If you've got 3 parties: Green, Yellow and Pink. 40% of the people vote Green, 30% vote yellow and 30% vote Pink. However, Green is supported all over the country, whereas Yellow and Pink are more regional, so in every district, Green gets 40% of the vote, whereas one of Yellow and Pink gets the other 60%, while the other gets none. Despite being the largest party, Green gets no votes.
Or let's say Green and Yellow each gets 40% of the vote and Pink gets 20%. All votes are distributed reasonably evenly, so about half of the districts are won by Green and half are won by Yellow. This sounds reasonable, until you realise that the Pink voters get no representation at all. It's possible to have a system where even a majority of voters wouldn't be represented, as long as the two largest parties manage to keep the smaller parties divided.
And in the US, that situation has devolved to the point that many voters don't even bother to vote for the smaller parties anymore, because they'd be throwing away their vote. And instead, they vote for candidates they disagree with because the only other viable candidate would be even worse.
Just use proportional representation. That's the only way to ensure that all political opinions get represented. It's not perfect, because nothing ever is, but at least the system is flexible, and voters can vote for completely new parties if they disagree with all existing parties, and those new parties can actually win seats.
