Perhaps, but no one is perfect. Keep in mind that perfect opsec also encompasses physical security+surveillance, where intelligence agencies are much better than this than criminals.
People say that part of Ulbricht’s shitty opsec was that he left his laptop unlocked, but think of this - the FBI was already ready to grab his laptop the very moment he left it alone. Clearly, they knew he was the criminal well beforehand, and were just lying in wait for him to slip up just one single time.
All in all, this is really cool work. I wonder what it would be like to work for the FBI or NSA solving high profile cybercrime. I imagine it would definitely feel more impactful than my current FAANG position, even if the compensation would be lower.

Is there another laptop of his that they physically accessed somehow prior to distracting and arresting him? (I don't understand how someone could think from that story that the laptop seizure played any part in initially identifying him, since it was done by FBI agents in the course of arresting him pursuant to a warrant.)
No, the theory is that a zero day was used on Ulbricht and they knew he was guilty for a long time. Things like seizing the laptop was just theater to construct a parallel trail of evidence for the courts.
I understand that theory, but I don't understand what leaving his laptop unlocked has to do with it. As the FBI already had a warrant to arrest him when they encountered him in the library, they had already made a probable cause showing to a judge by that point. The probable cause showing isn't the same standard as the "beyond a reasonable doubt" needed for a criminal conviction, but clearly the FBI already believed he was guilty before they seized his laptop, whether or not they accurately told the judge about all of the evidence and evidence-gathering methods that led them to that conclusion.
It's unfortunately entirely possible that they didn't tell the judge about all of it, but it's still not as though seizing his laptop was the event that convinced the FBI that he was guilty, or even that they claimed to be particularly unsure about their suspicions before that.
