i never understood why they backed him though?

Don't libertarians like free markets? Why should the government intrude on contracts for drugs or murder?

The government literally had to show up for the market for murder, with their own offerings, on silk road before they even were able to attempt to litigate it. We need the government so badly, because if a dark market shows up their informants/agents might solicit murder! Completely circular logic the state used in that case.

Many things the administration are doing are gifts to crypto bros and libertarians.
