Your girlfriend may be disorganized and a poor shopper.
I have a single USB-C dongle in front of me that's the size of a large cigarette lighter that has 2 USB-A ports, 2 USB-C ports, an ethernet port, an HDMI port, and can charge a 15" MacBook Pro. It cost $40.
Because your girlfriend bought a bunch of different items instead of a single solution, and can't keep track of them, doesn't mean that Apple screwed up.
