geofft's answer is funnier, but I think the more likely answer is this:

Realistically speaking, cryptocurrency-related crime is never going to stop being easy and profitable unless there is a massive increase in both a) government control over the internet and b) coordinated international law enforcement, since these crimes are usually international. Since libertarians typically oppose both, they are incentivized to make crypto-related crimes-- even when they're the victim-- seem like no big deal to avoid helping to fuel an outcry that might cause politicians to take action and bring about a) and b).

Granted, that's all quite speculative, but empirically, I have seen quite a few people get robbed blind of their cryptocoins and be remarkably sanguine about it, and I'm struggling to come up with another explanation.
