Bitcoin is neutral decentralizes money that provides the basis for a fully automated and permissionless monetary system that completely works without banks. Banks and their permissionned Financial system that is owned and run by a tiny elite and completely controls global capital flows is at the very core of the capitalist system. So it's a good start. It's also not property that extracts wealth from the work of others, it's pure money and hence I have no moral issues holding it to store wealth. But it can not end capitalism on it's own.
