I hear this repeated a lot but I don't believe it is true. You could either:
1) Connect to a monitor or other USB-C peripheral that supports sending power down USB-C, or
2) Use an adaptor that exposes HDMI or USB3, and also provides a USB-C passthrough like:

I realise that it is inconvenient, but I think its misleading to repeat the same inaccuracy over and over.
But if I have external storage plugged in (I'm copying a large file), and I need to charge the laptop, then I need to disconnect the drive in order to charge the laptop?
There are countless examples where daisy-chaining these devices becomes very inconvenient.
I don't really get the vision behind 1 port, but I don't get the angst either (not buying things is pretty easy).
(I continue to suggest not buying computers with 1 port as a great solution to the problem)
For instance, I often work outside and keep my charger at my desk inside. Sometimes I'll start something, check in on it in 10-15 minutes, see its going to take a while to complete, then go plug the machine in, inside, if it's going to take a while.
Sure, it's not something that can't be overcome (I'm not suggesting it is), but the need to check my battery (and to remember to check my battery) before doing something is an unnecessary inconvenience.
It's almost like I'm saying how wonderful the magsafe connector is for when I trip over the cable, and your response is "well, you don't need that—just don't trip over the cable". Sure, I don't need it, but it's just better with it.
But the latest Google Chromebook "Pixel" has two USB-C ports on either sides of the device.
