I saw that article earlier when googling for some info on Ross Ulbricht. The thing is, the vast majority of them will get away but the ones that are caught will send a message of fear across the deepweb but it's never going to stop them as there's people always willing to take risks. Prison or the death penalty doesn't stop bank robberies drug dealers murders or rapists and jail wont stop the tor markets. What it will do is force people to find new ways to stay safe and develop technology to evade capture. I look forward to one day when markets continue to run indefinitely without interference from the governments. Maybe eventually they will get the message and concede defeat.
