That explanation would only hold water if we were dealing right now with all kinds of problems stemming from lack of authoritarianism and too much freedom. I'm not really seeing it but maybe you have something in mind.

At least some people believe we do and vote for it. I'm not among those people and I don't hold this position, but somehow it gets more and more support lately.

"about to learn the hard way to put them back" would seem to imply you expect some real consequences from the lack of "fences".
