That's my point, its a trade off. Who decides what 'limited' means? The answer is the that it depends who already has the most power. In China, you can be certain any new e-currency of any form will be completely controlled and monitored by the central government. But in western democracies, there is at least a chance that a negotiated balance between oversight and control needed to prevent crime, and privacy and autonomy for citizens. But there has to be that balance. A completely unpolicable currency/financial system is just as bad (but in different ways) as a completely policed one.
