Let me insert my "5++" kilocents into how zcash should

be positioned (and how it would have been positioned/adopted from day one). You are allowed to believe or not believe in one G-d and his messengers (including prophet Mohammad). Regardless of this fact, there is 1+ billion of muslims around the world, including U.S. (see for example a professional boxer Mohammed Ali, congressmen Ilhan Omar, Rashida Tlaib). For a muslim (if he or she is true muslim and not just a clown) Quran is number 1 source of law. Does Quran say something about money? Well, yes.

3.118: "O believers! Do not associate closely with others who would not miss a chance to harm you. Their only desire is to see you suffer. Their prejudice has become evident from what they say—and what their hearts hide is far worse. We have made Our revelations clear to you, if only you understood."

It implies that information about your money (including: the amount of money you posses, how much you spent, who pays to you, what you paid for, to whom you pay, what you pay for, etc) is private/confidential. You and only you (or your family, or private foundation, depending of your involvement) to decide who else allowed to have access to this information. And this is actually what zcash 'enables'.

Another point is: Quran forbids interest gaining loans:
2.275: "Those who consume interest will stand ˹on Judgment Day˺ like those driven to madness by Satan’s touch. That is because they say, “Trade is no different than interest.” But Allah has permitted trading and forbidden interest. Whoever refrains—after having received warning from their Lord—may keep their previous gains, and their case is left to Allah. As for those who persist, it is they who will be the residents of the Fire. They will be there forever."
2.276: "Allah has made interest fruitless and charity fruitful. And Allah does not like any ungrateful evildoer".
3.130: "O believers! Do not consume interest, multiplying it many times over. And be mindful of Allah, so you may prosper."
4.161: "...taking interest despite its prohibition, and consuming people’s wealth unjustly. We have prepared for the disbelievers among them a painful punishment".

But as you know most (if not all) of the so called "fiat" money are emitted or distributed by interest gaining loans, or by the so called "fractional-reserve banking", which is actually emitting money out of thin air. There is pretty good documentaries in youtube on these topics.
As you know, zcash can not be emitted out of thin air, and this is why it is a "must have" money for muslims.

tell this to saifedean ammous. he will hate to hear it. he is a bitcoin maxi

I don't know who is he. Anyway, he is only one person, but there is a billion of others. I'm trying to explain things to russian speaking audience. But it is only a small fraction + russian speaking muslims is a minority from that fraction. There is also european, brittish and american muslims, some of them are rich enough and involved in social media. This is where we should aiming to.

zcashtrophe banning interest seems pretty ridiculous

he wrote the bitcoin standard.

I didn't say zcashers have to ban interest. I have reminded that most of the so called "fiat" are emitted by: 1) interest loans; 2) fractional-reserve banking, which is generating and distributing 'money' out of thin air. There is a lot of videos in youtube of the social impact. There is the book by H.Toxopeus (written 10+ yrs ago) which explains everything in details. And it is not funny at all. Actually you can not use fiat currency without feeding this machine (in one way or another) by the energy of your life (and thus the energy of the people you trading/working with). There is just no such option. So people with different mindset (or different notion of what of what is "normal") should have an alternative. I pointed you those kind of people.
