OK, at whose expense are you sauntering down the street, and how does this sauntering apply to " possibly enrich themselves at the expense of others"?
Still not the right question. At whose expense were resources just sitting on the shelves during the great depression, there being no purchasing power nor incentive to give those goods away?
OK, then who owns the raw materials, and who owns the bitcoins I control?
"Libertarians" being advocates of private property, isn't that a question for them to answer? Can one own a sequence of bytes?
Hmm. No meaningful posts. Only answers questions with more questions. Has no point, no connection to the discussion other than quoting. I think we've got a troll here.
