Cash is difficult but not impossible to track, Bitcoin is ridiculously easy to track by comparison.

PS: For comparison you can fedex ~170,000$ worth of gold in a vary inconspicious 15 LB box. Shipping ~60,000 lb of gold (1Billion$) is much easier to track and more risky.
"voluntary trade" makes it sound like said trade wasn't actually illegal (in
other words, like something the police are actually supposed to stop, peaceful
or otherwise.)
No it doesn't make it sound like that. "Voluntary" is not synonymous with "legal". The quality of voluntary trade is that both parties to it want to be in it: it's consensual. Many consensual actions are illegal, and some would argue that is oppressive. Left completely unmentioned, is the fact that Bitcoin is designed, and intended,
to make it infeasible to track users and enforce laws against transactors.
Yet they tracked Ulbritch, who was using Bitcoin and Tor. If they dedicated the same amount of resources to catching this extortionist, I think it's pretty likely he would be found.Just because something is illegal doesn't mean it's wrong.
But the police don't arrest people for breaking ethical principles, they arrest people for breaking laws.
So also, in context, not entirely relevant.
...Unless the police officer has ethical principles, in which case they will refuse to obey unfair laws. I remember watching an interview with a Danish cop that refused to arrest someone for smoking marijuana inside their own house. I think it's fair to say the government police system encourages unethical people to become cops.
They absolutely do. For example, police in Seattle explicitly made marijuana enforcement the lowest possible priority years before Washington legalized it. It was a common sight to see policemen standing right next to people openly smoking pot on the street and completely ignoring them.
The police actually have a huge amount of leeway, and it can be a big problem. They often decide who to prosecute and who to ignore, and their decisions are often driven by race, revenue concerns, or other issues that have little to do with justice.

If you disagree with the morality of a law, fine - but your assertion that enforcing drug laws is as immoral as enforcing slavery laws is debatable
If you want a legal precedent, the Nuremberg trials somewhat settled that question.
This is meant to suggest that the police were harassing innocent people while completely ignoring the actual crimes described, of course playing up the typical Bitcoin narrative of the violent, thuggish and incompetent police state.
Left completely unmentioned, is the fact that Bitcoin is designed, and intended, to make it infeasible to track users and enforce laws against transactors. It's an explicitly anarcho-capitalist system. Extortion rackets around Bitcoin are not a bug, they're a feature.
