There should be a mechanism on the blockchain level to settle conflicts. Bitcoin doesn't have any, and neither does Zcash as far as I know.

The beginning is easy when there is a company, but if Zcash is successful, it will start to decentralize and there will be lots of different opinions on how to handle things. If there is no consensus mechanism on the blockchain, there is a high risk of long and bloody fights.

I wrote about this in the Zcash forum: https://forum.z.cash/t/why-a-bitcoin-clone-and-not-a-dac/340
