To be fair, all of this means government protection against harmful, unfair action against you.

Even if they don't sanction it, can they actually stop you from doing as you please with an asteroid, obviously assuming you somehow had the resources? I mean, would they actually block a private launch if the company behind it showed technical capability to do this in some kind of responsible way? Who cares about somebody stealing it or somehow ripping you off in your ownership of this thing, how would that come into play here?

Sorry about the internet tone - not meaning to sound like I'm arguing, I am genuinely asking!
