Congress can still delegate certain powers even after this.

And every time they will, the courts will find that the delegation is not specific enough.

Never mind that congress appoints the heads of the agencies, writes the laws directing them, and on an annual basis, renews funding for them.

Adding on to this:

In addition to funding renewals, congress can make specific tweaks at any time to correct anything they dislike with regard to the executive branch. The ruling pretends like this avenue hasn’t existed and been used the entire time.

Maybe, but since this ruling just happened today I think we will have to wait and see what happens.

What will happen is that anytime someone doesn't like a regulation, they'll now have many, many jurisdictions in which to shop for a judge that will rule in their favor.
