It seems to me limits on accumulation prevent it from being widely adopted. If as a technical limitation there is a limit to how much wealth you can have accumulated in the coin, why would you even bother with it in the first place?
It depends upon where the limits are placed. How much more valuable should one human being be than another? This is the philosophical question that all of us need to settle within ourselves before we can move forward as a species. Once you have wealth enough to ensure sufficient comfort for yourself, your progeny and theirs, all other accumulations are about power and/or some other perniciousness.
