Part of freedom is the ability to pursue happiness in ways which respect other people's ability to do the same. That means we need to respect everyone's right to do just that as long as they respect ours. The more ways we have to pursue our happiness, the better chance we have of finding that happiness.
Happiness doesn't depend on money, but money can't hurt. If we don't have paper money (or paper money is worthless), and we don't have hard assets, perhaps cryptocurrencies can fill the gaps for us. Cryptocurrenncies are for everyone, we just need to learn how to acquire them and show others how to acquire them.
