Life isn't fair.

I can think of one surefire way to make something worthless though, give it to everyone for free.

Why would anyone value something that required 0 effort to obtain?

The OP seems to be making the mistake that early adopters were given coins for free and risked nothing. This couldn't be further from the truth. They put time and money into Bitcoin at a point when it was almost guaranteed to be worthless at some point in the future. They risked losing everything they invested. Because they took those first steps, they paved the way by showing that some people value the properties of Bitcoin. This led to others learning about Bitcoin and assigning it value themselves. Each person who values Bitcoin gives value to the entire system. The system wouldn't work any other way.

OP, if Bitcoin is so unfair, I suggest you do something about it instead of complaining. Create you own currency and give it to the world for free. I think you will learn quite a bit and come away with a different point of view.
