I think the biggest trick is to move around, so it isn't as simple as getting a single address. Like with Bin Laden, a lot of the work was figuring out where he was. And Ross Ulbricht, maybe he wouldn't have been caught so easily if he changed hosters occasionally and the VPN had listed 100 internet cafes in different cities as connecting IP addresses instead of just 1. Certainly that's the way Tor works, always hopping around routers. It's maybe a bit pointless though, once they get your legal name it's pretty much a matter of time.
So if you get high enough on the list, it’s like those ‘immortal snail’/snail assassin scenarios.
Even Bin Laden got taken out and dumped in the ocean eventually.
So like Jan 6th - it had better work, or your goose is very likely cooked eventually.
