I agree with the overall point you're making. The only problem is finding a way to stop criminal activity on OpenBazaar. If it truly can't be taken down by "tradional means" like D Dosing, etc, then the only other options I see would be taking down the nodes, or w/e keeps it running,
Exactly, Investigators will actually have to commit real man power and conduct formal investigations thus making the costs of regulating drugs/piracy/gambling/guns much more expensive.
This is a great thing if you believe in personal freedom and that victimless crime laws are unjust and immoral. Otherwise, if you are a control freak, and you can't stand the fact that someone has the right to peacefully exchange good and services that you don't approve of than good luck trying to shut it down.

The beauty of this technology is statists political beliefs don't matter.... history is unfolding and you need to brace yourself for a much more liberated society and deal with the repercussions both positive and negative that come with such.
...There's a limit on "Personal Freedom". As long as your freedom doesn't affect anyone negatively, then ok. But when things like childporn, sex trafficking, giving/selling people narcotics, comes into play, that's an abuse of "Personal Freedom". That's also exactly the reason why these things should be outlawed. What you're talking about isn't freedom, it's the destruction of other people's lives at the cost of your own temporary happiness. Which is exactly what drug dealers, child molesters, sex traffickers, and more do.
