As for people acting irrationally, in most cases they should have the liberty to do so as well. I'm not much of a libertarian . . . I'm a free-market conservative. Ronald Reagan observed that the two travel along the same path.
From what I have seen of your arguments, you are are neither for a free market, nor a conservative.
On the free market, Reagan rejected your definition of market freedom, as he astutely recognized the games foreign adversaries played, hence he DEMANDED bilateral fairness when dealing with the stacked decks they set up. Reagan also recognized that small American manufacturers...the very fount of creativity, needed special warding against foreign governmental monopoly attacks.
He would have been especially dubious of the freedom of international markets dominated by a communist tyranny such as China. Why do you think he was so zealous at strangling the Soviet's from our capital and technology?
Nor are you particularly conservative since you don't seem to care a wit about national defense, let alone our industrial capacity to sustain it.
