This is not an accurate description of that decision.

Agencies no longer get special privileges in interpreting the scope of what Congress delegated to them.

Within the scope of what Congress delegated to them, they still have an much power and discretion as ever.

There was an argument about noncompetes and the FTC in front of a Federal judge recently.

The judge said, "Even as the agency has the power, I don't feel sufficiently convinced by their argument and will block it anyway."

That doesn't sound like they have as much power in their delegated responsibilities if an arbitrary judge says "... and you also have to convince me personally, even though you're entitled to do it."

if Congress wanted to delegate decision making to the judicial branch they can pass laws that do so. they pass a law saying that the agency can make decisions, those decisions should be respected. this decision is right the equivalent of if the courts decided they had the power to block laws that the court thought were bad policy

You should read about the non-delegation principle and why it exists. As Wikipedia says, “It is explicit or implicit in all written constitutions that impose a strict structural separation of powers. It is usually applied in questions of constitutionally improper delegations of powers of any of the three branches of government to either of the other, to the administrative state, or to private entities.”

What you are proposing is that Congress be allowed to abolish its own power, completely destroying the constitution.

Who cares if they had that ability? They wouldn't use it.

And even if they did, it wouldn't violate separation of powers.

And even if they did, they could make a new law that takes it back.

Of all the worries about delegation, this one seems like the least meaningful.

Federal agencies now have oversight from the judicial branch. That's a big check on their power.

> now

They always have?

Much less.

Yes. Previously the court had to prove that something an agency did went against the mandate congress gave it, to strike it down. Now it can just strike it down for no reason. This is useful in times when republicans control the courts and democrats control the executive.
