Bitcoin's barrier to entry is having the appropriate level of understanding to realize that there is a need for a system of value transfer that is outside of the reach of those who would choose to exert control over everything.

Anyone who is willing to sacrifice their freedom for alleged temporary security has no reason to use Bitcoin.
