You're comparing facts: "Ulbricht ran The Silk Road," with your own conjecture: "Banks encouraged 'questionable' risk taking." You're making a lot of extraordinary claims that are very very difficult to prove with no evidence to back them up.
And you're using this conjecture as evidence of... something? You don't really make a point. You just repeat popular internet tropes.
When people that have clearly violated the law - like certain people in the CIA, for example - are not even prosecuted, it is hard agree with people that think it is "just" to give someone life in prison for allegedly committing as far lesser crime.
At worst, Ross Ulbricht is accused of an attempted conspiracy of murder. People in the CIA actually killed people, in ways that are always illegal.
A lot of people were defrauded. The economy is still trying to recover. I don't think people who lost homes or are struggling to find work and make ends meet would consider any of this to be an internet trope.
