Unless you want to use your external display as power supply and usb hub at the same time with just one cable.

Some of us do work in actual offices and not in some coffee shops down the street. ;)

Whoah, what's up with that? Not sure why you're inferring this coffee shop story or why you're doing this smug posturing thing but it's pretty obnoxious.

but it’s not what parent author wrote. idea was to use usb-2 cheap cable as a cable to transfer electricity between charger and laptop.

USB 2.0 specifies a maximum of 20AWG wire width for power transmission, which would limit you to 1.5A for charging.

We're talking about usb-2.0 data over usb-c cable. It'll still have the power delivery of usb-c

And that wastes physical real estate that could be used for a more modern cable. And with more USBC / thunderbolt cables around, theyll also get cheaper.
