So far I have seen some people arguing for 100% privacy, and some for (pseudo)privacy as it is now in bitcoin. (It is pseudo-privacy and not privacy, you can't be 100% anonymous with your transactions on a public blockchain free for anyone to view, no matter what tricks you use like Tor, mixers etc - if you are still not convinced there are several articles/academic papers out there that show exactly that).

I would suggest that to concisely answer the question, you have to look at the big picture, not yourself as an individual.

Let's say I am using fiat money. I get paid my salary to my bank account, I pay my bills, my doctor, I buy my vacation and my sex toys.
Q: Do I have the right to keep these transactions private?
A: Of course I do!  I don't anyone to be able to take a picture of my entire life just by looking at these transactions (not my friend, my neighbor, my employer or the government). Nor do I want to advertise my savings amounts to the entire world.
Q: Does bitcoin (as it is today) help me keep these transactions private?
A: No (see above). => Bitcoin as it is today can not be used as a total fiat currency replacement.

Now let's say I am an illegal materials/goods trader (drugs? child pornography? human trafficker?) or I am otherwise engaged in some criminal activity (money laundering? blackmailing? scamming?)
Q: Do I have the right to keep these transactions private?
A: NO. Authorities will have to suspend your privacy rights if you are suspect of taking part into illegal activities.
Q: Should authorities "unmask" your private transactions in such cases?
A: Yes. If you are part of an organized and lawful society you should think the same. If not, go find a place to live in some anarchist country on in the jungle with the monkeys.
Q: Can a 100% private - anonymous cryptocurrency (Zcash?) be auditable and accountable for such illegal transactions?
A: No. => Such a currency can not be used as a total fiat currency replacement.

Now you might argue that Bitcoin (or some other cryptocurrency) might not totally replace our fiat currencies but could somehow be a global-"subcurrency" that could be used for some types of transactions (e.g. capital transfer across countries). Such thing might be a possibility.
But those who dream ourselves living our lives only with cryptocurrencies, I think that a cryptocurrency that satisfies the properties "anonymous" and "accountable" will have to be invented first.

I added a poll to this post to see what your opinions are.

The hardest thing is to be your own boss. Every one has a different work style, but if you want to start a business, a provider for emploings then you must know in what you are going to step in because everybody involved depends on you.
