You can get cables longer than 2m. I have 4m usb-c cable for charging my computer. And as for dongles, most people will need only one. And it's not like with other computers you don't need any dongles. Lottery with display connectors was always PITA (vga, hdmi, mini hdmi, micro hdmi, displayport, minidisplayport, dvi, mini-dvi). Having usb-c for that should finally solve this in some time.

Then there are the Flash Memory readers...
