I am grossly unqualified to answer this, but I'm going to anyway because it's the internet and you can't stop me.
Sometimes when a group of bullies does bad things, each bully only does a little bit of a bad thing, but all the bad things together make for a really, really bad thing. Before RICO, good guys could only punish bad guys for the little bit of the bad thing they did. But with RICO, the entire group of bullies (be it an organized crime family, a corporation, a political administration, etc.) all get in trouble for participating in the overall really, really bad thing.
This is especially helpful when the leaders of the bullies barely do any bad things at all and just instruct (or even imply for) others to do bad things. The leaders can get in trouble for that, and the regular bullies are even encouraged to to give the good guys more information about the leaders so they (the regular bullies) can get in a little less trouble.
Ghouliani would have been one of the attendees at the original pre-election coup kickoff planning meeting, along with Steve Bannon (who confessed on video), Roger Stone (who also confessed on video), and Convicted Sex Offender Treason Trump. I wonder if anyone else was in that original meeting?
