"Maybe. I'm never really sure what people mean by libertarian. It clearly means different things on opposite sides of the pond, but from what you say below, and the times you have described yourself as a minarchist, I take it you pull up short of the full blown anarcho-free-trade-capitalism."
Libertarianism has a lot of strains and most of 'em tend toward consequentialism. Me, I'm a natural rights guy, makin' me a rare animal (cuz natural rights/law is not favored these days).
This...

...is a decent overview.
My specific view: The individual owns himself. The individual has a right to his life, liberty, and property, The individual's life liberty, or property is only forfeit (in part or in whole) when he willingly, knowingly, deprives (in part or in whole) another of his life, liberty, or property. Some individuals can't self-defend or can't self-defend across all circumstances, so instruments are used to offer defense and compensation: a sensible, minimal court of last resort, a sensible, minimal constabulary, a sensible, minimal, border-stationed military, and a militia to rule the other three (the first three are employees; when they look to dis-embed themselves from that subordinate position, the militia - every other armed person in the minarchy - is empowered to put them down).

"Bear in mind that, to the Crown, the entire empire is an asset."
Sure, I get that. It's competing notions: does a man rule himself, or is man (meant to be) ruled another?

"I imagine he was aware of the French and American revolutions and thought they were a good thing."
Marx was an awful person, so I don't care what he thought.

"No, you are not going to teach that creationist bullshit!"
In a private school, one funded by the folks who send their kids to it, they can teach whatever they like.

"how do you "force the economic elite" to do anything that will cost them money?"
Violence of course.
The violence of the ballot, or the violence of the gun. Me: I have almost no faith in the ballot.

"Well, the cool thing about guns and motorbikes in Odin's Hall is that everyone is already dead."
Exactly, so: go nuts!
