Why is it that morals are so simple as children, (the golden rule applies to most moral issues) yet so complicated and perverted when we grow up? Simple, it's because we have to adapt to this immoral system, namely our government's monopoly on force. At the same time we must convince ourselves that we are not immoral even though we enable this system.
Let's say you are a school teacher, everyone loves teachers! You are paid with dollars which are extracted by force from the population. Should the population pay your salary? If yes, first realize that a sizable portion of that money will be used to pay bureaucrats. Next, realize that the continuation of government schooling hurts private schools (costs go up, demand goes down), parents (have to pay twice to enroll child in private school), and kids (are taught to take tests, not learn what it takes to survive and thrive in the world). Also realize that once the private institutions are marginalized, innovation grinds to a crawl.
So let me ask you this, reader: do you make your livelihood through voluntaryism (mutual trade), or does the institution you work for accept money from the government or exists because of the monopolies granted by government?
I think it is important to understand the philosophy and morality of voluntaryism when trying to understand the legality/morality of bitcoin and it's uses. Here's an example of how people often misdiagnose the problem:
If many thousands of people started using bitcoin as a Western Union proxy, (cross-border money transfers), the US would have massive problems keeping inflation contained to certain areas. Most people look at this situation and realize that bitcoin can cause disruption in currency markets, therefore bitcoin should be regulated. However, people generally don't have any idea how corrupt the dollar monetary system is. What people fail to see is that our currency is so corrupted that honest, voluntary exchange is a threat to it.
Does it really make sense to jail people for inhaling smoke from a plant? No it doesn't, but jails are filled with drug abusers. This only works because one herd of sheeple is pitted against the other...NOT because of overwhelming government power. However, this policy does increases government power.
The next time a law passes which bans voluntary action, ask yourself...is this justified? (i.e. ANY law related to bitcoin...hint: the answer rhymes with snow).
