Fortunately in service of Wright's big fraud Wright commits lots of smaller frauds, and some of those are provable to a very high degree.  In the Florida federal case wright was already judicially found to have fabricated evidence and committed perjury.  Unfortunately, so far the only direct consequence is a few hundred grand in penalties and some adverse inferences.

But he's also engaging in the same kind of ultimately provable perjury in every other case. If you look at the history of conmen you'll see that it often takes years for them to be brought to justice.

At this point I also wouldn't bet that that his core fraud couldn't be proved beyond a reasonable doubt-- the primary challenging blocking that is just the lack of criminal investigation powers.  Keep in mind: even though there is so much evidence of his fraud out there, he ultimately published almost all of it himself-- his discovery was self-produced!  We haven't even started to see the kind of stuff that will get exposed by a real investigation, where he can't stuff the record with forgeries produced on the spot or hide things he doesn't like.  If this crap is what he wants the world to see, consider what he doesn't want the world to see?  Consider what testimony might become available when his supporters are facing the risk of criminal prosecution and jail time themselves?

Somehow people get mixed up about what proof means in a criminal context:  We convict people of murder all the time, yet none are ever proved guilty in a strong mathematical sense.  Instead, we have the body, the motive, the fingerprint covered murder weapon, maybe a video recording, even when there there is a confession that isn't proof-- false confessions are common...

In Wright's case, his numerous forgeries and lies are the bloddy murder weapon, the victims that funded his Nigerian scam on the basis of of his promise to dump bitcoin buy BSV as well as his false claims to try to steal Bitcoins and get control of bitcoin.org are the body, his tax rebate fraud, profits, and the litigation show his motives, and so on.
