3x systems are really more of a vestige of "More Speeds!" marketing that was devilishly effective against consumers. Secondarily, there were the engineering reasons:

  • A desire to reduce chainwear through cross-chaining
  • Limitations in derailleur reliability on the front chainring: To get to a small front chainring you needed a useless one with duplicate gearing in the middle

1x is all the rage right now for many of the reasons you've stated, and because the cycling industry has to reinvent what's popular to sell more. 2x Drivetrains have the same-or-greater ranges than the 3x systems of old. Note that 6/7/8-speed bikes all use the same chain size, and 8 is the most ubiquitous gearing out there. Once you get to 11/12/13 every drivetrain component is more expensive and proprietary.
