Certainly less than reinventing the wheel. You have to include development cost, maintenance and so forth that is not needed or significantly reduced on hosted content delivery services. See my post in this thread for details.
They can at the scale of the NPM registry, but I don't imagine some of the lower-end CDNs would be that much more expensive than scaling up the backend to meet demand.

CDNs cost a lot of money.
