Fortunately, privacy won't go anywhere soon thanks to anonymous cryptocurrencies like Monero and Zcash. While governments can impose regulations to restrict or even ban the use of privacy coins, they can't be enforced because of the decentralized and censorship-resistant nature of crypto/Blockchain tech. I hope crypto remains that way in order to minimize government's power over the people as much as possible. Just my thoughts

I'd just like to point out that Zcash always relied on a set of private keys being created and exchanged securely in a so-called 'ceremony' made by a set of people (developers) when they started the project. I wouldn't trust a dime to a system like this.
Apparently, they planned to move away from this in May (last month), but the text is still in past tense, so I have no idea if this ever happened.
In May of 2022, Zcash will begin using the Halo 2 proving system, which removes reliance on a complex setup ceremony and upgrades the underlying cryptography. But when Zcash launched in 2016, its zero-knowledge proofs required a setup phase to produce public parameters that allowed users to construct and verify private transactions.
At that time, some random numbers were sampled (which we refer to as the “toxic waste”) and were then used to construct the parameters.
After the setup phase, the toxic waste had to be destroyed to prevent counterfeiting of Zcash.
