Most libertarians I know are reasonable libertarians. They want some service and regulations, they just want such to be minimal and to be served by the lowest and most local level of government. Just enough for basic safety, a level playing field, equal opportunity and most importantly accountability to locals.
I'd argue that in California, the biggest contingent is what are sometimes called "liberaltarians" (I include myself in this group): secular, very libertarian on social issues, skeptical of interventionist foreign policy, broadly pro-capitalism, generally just want to mind their own business and make money and be left alone, but don't usually freak out over income taxes and mildly redistributionist policies and universal healthcare, and probably more environmentally conscious than average. Personally, I despise laws banning smoking in private business (e.g. bars), or requiring seat belt or bike helmet use, but on the other hand, I think California's law declaring the coastline public property was one of the wisest things the state ever did.
Most of us are willing to put up with the large number of crazies in the Bay Area because overall, they're not nearly as powerful as you might expect (outside of Berkeley, at least), and they also like weed, gay marriage, and Mexican food, so at least we have that much in common.
