Much like the difficulty in taking down the mob, the reason that Trump is walking free today is because nobody around him talks. We all see the criming taking place but the threshold to gain conviction in a court of law is so high that you need witnesses. Think about how many times Trump has attempted to exert executive privilege and Attorney Client Privilege. His goal is consistent. Delay, obstruct, delay, run out the clock, appeal, delay. (and run for office so you can claim everything is political).
So the fact that Trump's own lawyer in the stolen documents case must turn over his communication motes and testify about his conversations with Trump is a breakthrough. And the only way that was done is if it was proven that their conversation involved planning and committing crimes. And the speed at which the judge wanted action and any appeals was unprecedented. Indicated there might be a serious national security thread involving this case. Evidently Trump lied to him (big surprise right?) and that gave him legal liability and now he is perfectly willing to sing like a songbird instead of going down for Trump.
Does the lawyer know that there are still classified documents in the wild? Did Trump give them to other 3rd parties? This is really bad for the Orange traitor. The porn star payoff is the least of his troubles. Almost a side show for the media compared to the seriousness of what Jack Smith is investigating.
