I liked the comment explaining where Internet Libertarians come from:
And if you grow up in your parent's basement, then you are shaped by an environment where the fundamental constraints on what you want to do are shaped neither by scarcity nor malignance, but _by genuine good intent_. Your relatives probably don't wan't you to spend all day smoking pot and playing video games; in some cases they will over-estimate just how much of a bad thing that is. And even if they _are_ right, it's not like anyone facing such hectoring is going to admit it.
Pretty much every libertarian position can be understood in that frame of restrictive but benevolent authority being the root of all 'real' problems. It's a rare parent who literally tortures their kids, so torture is, at best, not a 'real' issue, not a priority. But many make them do stuff for their health, so mandatory health insurance is a big deal. Pretty much no parents kill their child with drones, many read their diaries. And so on.
So to libertarians, Bitcoin is like wages from a fast food job as opposed to an allowance; lets you buy what you want without someone else having a veto. Only money that doesn't judge you can be considered entirely yours...
