Torpor Orb effects being 2 mana made them too late for many strategies in eternal formats. This is what a Modern-playable Authority of the Consuls would look like.

Well, hate answers shouldn't be too cheap. Instead if you want this early, then make it like a leyline so it's on the field before the game even begins.

That's true to an extent, and this is an effect I would consider making a leyline. But we do have precedent for similar cards at this cost (like Authority of the Consuls). By replacing the 1 life ETB with the hush effect, the card becomes more useful than the narrow use case AotC had in KLD-AKH Standard vs RDW. I feel that the built-in drawback with cards like this is that they do not affect the board when they come down and are therefore terrible when you draw them late (so I don't think it's too powerful).
