Government doesn't "enforce" responsibility. Despite what they're selling, TANSTAAFL.

Freedom and responsibility can not be separated, and there is no need or want for artificially added, or subtracted, responsibility.

For those in the US who disagree, they should be thankful that they're still free to leave, and go anywhere else that doesn't exist for the sole purpose of protecting the rights of the individual. It is inappropriate to stay in the US, or worse come to the US, and try to violate the rights of the individual because you're too afraid of freedom, or the inherent responsibility.
