Hundreds? Really? Of course everyones' needs are different, but I'm doing fine with two USB-C to USB-A 3.1 cables at $9 each. And a USB-C to RJ45 Gigabit Ethernet adapter for $15.
Do you leave the dongles attached permanently? Of course, you might want to attach a Bluray drive and printer and ethernet and external hard drive so you might want a USB hub.
I have to say, my laptop with bluray drive attached to a USB hub attached to a USB dongle --- it doesn't look as elegant as it might.
I'd have appreciated even a single USB-A port - for USB drives etc.
And of course when, in say 10 years, everything does indeed come in USB-C ... then they'll come out with USB-D. Because it's 0.2 mm thinner.
