Then where you draw the district lines doesn't matter nearly as much because no matter where you put them, the candidate that pleases more of the voters in their district has the advantage, which makes it hard to disenfranchise anybody.
By removing spoilers from the equation you can have two highly similar candidates running against each other without splitting the vote and both losing, so a candidate that satisfies more of the district defeats one that disregards the concerns of 49% of the voters.
It also makes it much harder to gerrymander for the advantage of a particular party because it would make third party candidates and independents viable, and shifting voters around would have hard to predict results on party balance. Moving some Democrats you "didn't need" from a Democratic district to one that used to go to the Republicans might make the first district go to the Libertarians and the second to the Greens.
Colorado is an interesting case because it accidentally reveals a degenerate solution. Geography and population form boundaries in the denser areas, but not the sparser ones.
