A successful coin will emerge, but it will be one which doesn't need a fair launch.
I agree that a coin doesn't necessarily have to have a "fair launch" to be successful. But I don't agree with everything else you said.
The thing is, what's the incentive for people to use your coin? There is none. Remember, liberatarians are a very, very small part of the population. The rest of the people enter for 2 reasons:
1. To make money
2. When a coin becomes THE way to pay for everything, they kind of are forced to adapt.
With your coin, there is no incentive to join the network for the first movers, so there is never enough network effects for the people who enter for reason 2.
The "cost" for using any cryptocoin is near 0. You still keep the purchasing value of your fiat when you use fiat to buy the coin. For example, if I bought $100 dollars worth of bitcoins when they were $10 each, I'd get 10 bitcoins, which would buy me $100 worth of stuff.
If I buy $100 dollars worth of bitcoins now, I can still use it to buy $100 dollars worth of stuff. The cost is nothing. That's why people still can switch, even if they're very late. There are no penalties*. But early movers get an advantage to use it, so there is an incentive to enter before it's too late.
*Most people don't consider the opportunity cost. Such is the world.
