No, your cable modem would be 1.08 terabytes per day.
Does it stop making sense when your calculations for the Roman telescope indicate slower speeds than your connection, which you say is 1/5th the speed?
Now, since the Roman telescope will be at an L2 point, signal acquisition will always be subject to the Earth's rotation. So there will be multiple ground stations involved across the globe.
If the quoted rate by NASA of 1.5 terabytes per day is accurate, then it will not be downlinking 24/7, but in bursts. 500Mbps is also the max, where the actual range will be 250-500. We'll need to account for RFI and packet loss, etc.
