I survived with a 12" Macbook and a solitary USB-C port. The one difference is that I did have an audio jack as well.
I found a monitor that had a USB-C connection with charging, a USB hub, ethernet etc. (of which there were very few back in 2015). When I was somewhere other than my own desk, the Apple HDMI dongle was more than good enough.
The only "this sucks" scenario was when I had the opportunity to use multiple external models, but couldn't. Aside from that, I don't regret getting that laptop.
