Like someone named Charles Hitler wouldn't be Adolf Hitler, Hitler will always be associated with the Adolf Hitler everyone knows about, so Charles wouldn't be well received in the world with that surname, despite being completely innocent. ( #GoodwinsLaw )
Bitcoinism? Ownerism? Self-ownership? Proper ownership? I don't know what's best, but even if it is really capitalism, it needs a new name.
