We're expecting way more from our USB peripherals than we used to. It's either drawing power from USB or having an extra power adapter connected directly to the USB peripheral, and thankfully we're shifting towards the more convenient option. I'm not sure what this has to do with efficiency.

  There's no theoretical reason I see why USB would be worse than an external adapter with the same wire gauges. The only issue is that an expansion card powered by the PC supply would have an extra conversion step to get the voltage to USB-C levels. That's solvable though, maybe they could route the USB through the power supply itself. Or a docking station can power both PC and monitor. Maybe the next generation of PC parts will run directly on 48v or 20v.
