Any CDN worth its salt can run on your domain so that’s not an issue. The issue is that no third-party anything is pointless as links will just change from nyt.adnetwork.com to adnetwork.nyt.com. I’d rather not encourage those kinds of DNS shenanigans.
You’d tell cloudflare DNS “yo put your stuff on cloudflare-cdn.mydomain.foo”. Embeds should be iframes, that is, different webpages, imgur could do the same though yes it’s overkill. Another option would imgur offering an automated API that would allow cloudflare DNS to tell it “here’s a key, please get ready to serve on imgur-cdn.mydomain.foo”.
It can all be handled on your domain without you actually running the backing servers. It’s also insanity.
It doesn’t, but it defeats the purpose of CDN, because your users still hit your domain instead of CDN one and cannot leverage the benefits of distributed caching. Browser cache is bound to a URL, you change one letter and it is invalidated.
It won’t share js libraries and fonts and whatnot cross-site but compared to a single image that should be negligible. At least if you don’t pull in gazillions of superfluous dependencies and don’t even run dead code elimination over them. And anyway that’s more bandwith usage between user and CDN, not user and you.
Also I already said that it’s insanity. But it would work.
And how often do I have to repeat that it’s insanity? It’s just that user network traffic doesn’t even come close to the top of reasons why it’s a bad idea.
CDNs like CloudFlare reduce load on smaller servers through caching and delivery of common assets, which reduces load times (helping to democratize sites as it’s not just big companies that can afford quick websites). CDNs also prevent DDoS attacks and can improve uptime.
They’re pretty critical pieces of internet architecture. Not that they’re perfect, but banning all third party content from sites is kind of a baby/bathwater situation.
CDNs also reduce load on the network. Why pull a resource from a server on the opposite side of the world when a CDN on my ‘door step’ can provide a cached version of it.
The purpose of a CDN is to better cache common resources between different web sites. For example, if you’re using a Roboto font from Google CDN on your web site, just like many other web sites do, the user who previously visited other sites with such font will load your web site much faster and will spend less traffic, because he already has this font from CDN in their cache. It also means that you save money on hosting.
If you remove CDN from the equation, you punish yourself and your users. That’s a very dumb idea. Especially when CDNs are free to use.
No more CDNs is a bad fucking idea.

What about a CDN for JS libraries?
What about YouTube embeds?
What about images from Imgur?
Why should all of this be handled by me, on my domain?

No. Things being on your domain doesn’t mean that traffic hits your servers.
It doesn’t, but it defeats the purpose of CDN, because your users still hit your domain instead of CDN one and cannot leverage the benefits of distributed caching. Browser cache is bound to a URL, you change one letter and it is invalidated.
Why would the URL change?
It won’t share js libraries and fonts and whatnot cross-site but compared to a single image that should be negligible.

Because you’re not using a CDN URL everyone else is.
Savings are massive for the user. If you don’t care about your users, please stop doing anything development related.
You know what’s faster than a CDN? Vanilla js.

Insanity is what you have in your head.
Why?

Ah. Thanks!!
