We have them because the Founders thought it was a good idea.

Then they thought it was a good idea to have two houses with different criteria, giving two chances to quash legislation. Plus the veto. Plus the Supreme Court (whose job they left almost completely undefined, so they made up a job description).

So we have them because we can't get rid of them. But they are practically useless. They can usually manage the bare minimum of reauthorizing the thing they said last year. Then they can rename a few post offices, have some grandstanding hearings, and then go home to campaign for reelection.

Thankfully, the CFTC can't actually order Kalshi to continue operating in NY despite being in violation of NY law. They have no authority to override any judge's order/etc, and at least so far, have not pretended they do.

As for me, i've never pretended it's either normal or desired for the courts to make policy, whether congress is dysfunctional or not. Among other things. My comment was basically pointing out that the current supreme court seems perfectly willing to throw out decades of settled law on an ideological whim, and actually, for that matter, happily interpret very clear congressional statutes in very odd ways.

So your comment there is mistargeted, at least as applied to me.

absolutely nothing in going to happen in the US congress until 2029

we're essentially one year of three into one of the least effective lame duck legislative bodies we'll ever see
