I have literally done this once with a friend of mine, transfer a file over netcat. It cost us about 10 minutes of figuring out the exact commands, and we were at the same LAN party, and thus had a direct network path to each others systems. With most consumer routers and their NAT this would be much more complicated. And this was with a friend with high unix knowledge, so not just the "I know how to paste commands from askubuntu" knowledge. So yeah, just being able to copy curl commands from a website certainly has value over configuring complicated commands.
