Zcash will become the next money. That's because it contains bitcoin's solutions to fiat, and also solves bitcoin's lack of privacy.
Why not some other cryptocurrency that also has those features?
For example, why not an existing or future fork of Zcash?
“[Insert favoured cryptocurrency] will become the next money” is an extremely easy to vary statement.
Is "it contains bitcoin's solutions to fiat, and also solves bitcoin's lack of privacy" easy to vary? Could be made harder to vary by explaining the technicals of zero-knowledge proofs as well (though I'm not konwledgeable enough to do that here).
The part that is easy to vary is that an arbitrary amount of different cryptos can be made with the same features.
The features themselves can be as specific as you like but the overall argument is still extremely easy to vary, because it is an argument for a specific cryptocurrency.
It is the same as arguing for a specific god because the god you like has specific features. The god itself is still easy to vary.

I could still see someone with knowledge of psychology and theology provide a good explanation as to why certain gods and religions have spread in favour of others. All ideas are solutions to some problem.
It is one thing to explain why a particular god spread more than others in the past, but it is another thing to claim that your specific god of choice will spread more than others in the future.
Your claim is that Zcash is the next money, which is analogous to claiming your niche god of choice is under-appreciated and will be the next big one.
Yes. But again, because it solves certain problems with existing money. There could similarly be good and bad explanations why certain religions would spread in the future.

There's never an arbitrary amount of solutions to a specific problem. In this case, the problems are the centralisation and the lack of privacy of our current money. They may not be problems for you specifically (e.g. if you live in a high-trust jurisdiction), but I'd like to hear arguments as to why nobody in the world would consider them problems.
I don’t deny that Zcash might be decentralised and private.
For Zcash to become the next money, it is not sufficient for it to just be durable, fungible, private, decentralised, etc.
As long as it doesn’t have any underlying value, it will not be suitable as money.
You are using secondary attributes of good money as positive justifications for Zcash as good money, but you are failing to answer the criticism that Zcash has no underlying value.
