The government has had limited powers to regulate our life since the founding of our country. And every other government on the face of the Earth has the same. I agree that we have way too much regulation of our lives. But some regulation is necessary and essential. That is where libertarians are on the wrong track.
It is supposed to have limited powers acording to the constution, but it has assumed more and more powers during the last two and a quarter centurys. The founders never envisioned the type of over regulation and the intrusiveness of the current federal government. Their vision was of a realitively small ferderal government and state governments that would regulate, or not, the type of personal behavior laws that we are discussing.
As for every other government on earth having limited powers, well you probably didn't mean it that way, but if you did, I would remind you of North Korea, Cuba, Iran, Iraq, Sudan, China, Zimbabwa, Pakistan, Libia, etc. I don't imagine their citizens would share your views that their governments powers are limited.
