And also, yeah, some libertarians are idiots who just want to do drugs, or who think that a bunch of people doing drugs won't be a detriment to society. That is a very large minority of libertarians. A lot of us, on the contrary, recognize that it should be perfectly legal but that a rational person would stay away from it and that stores would certainly not sell them to kids, or that it should be legal but culturally discouraged, or that it should be illegal by way of a covenant community's rules but not by a government. Same for every other questionable thing.

If you think a government is the only thing that stands in the way of a majority of young men deciding to snort cocaine while a hooker who probably has STDs rides his dick to the sound of death metal, in the first class section on a rickety yet somehow expensive private airplane that was purchased just for this occasion on an installment plan denominated in a scammy Dogecoin competitor cryptocurrency, then you might want to rethink how much power the government really has. It's not what holds society together. A culture of self-reliance and rationality is self-sustaining. And it also tends towards libertarian economic systems.
