The actual number of people who care about libertarian ideals is not that high. Not enough to make bitcoin into a huge success, certainly.
You don't need to be a libertarian.
Remember that the number of people who like their national currency to be devalued and devalued and devalued is a very small group. Bitcoin offers a deflationary store of value, like gold, but you can also pay with it directly and electronically all across the world.
People in western countries or rich countries do not understand the problem. However billions of people live in countries where simply holding fiat currency for, say, 3 years, will end up in a reduction of your wealth by something like 20-40%. And these countries will also try to make it hard for the citizens to obtain hard currency or gold, in order to reduce pressure to their respective national currencies.
