Privacy is a necessary feature in my opinion, but why hasn't Monero become a main coin?
I dont think monero is so unpopular than it shoukd be, monero is still very early as an altcoin and it offers a superb privacy that even bitcoin couldn't give, monero would olny be of interest to those that needs its service in a way or two and that should be amongst people that already know about crypto in a way or two, so expecting to hear about monero from new users or peole ealry in crypto or on major crypto news would not be a realistic thing, and besides most new investors come in because of wanging to make profits and right now monero is not that coin and shouldn't be cause if it enters the spot light and government gains attention to it, could lead to its downfall like the silk road market place that offers quite the anonymity like monero.

Not all investors will value the term privacy when dealing with crypto as the purpose of creating monero is to promote anonymity, investors still go for coins with higher profit and zero privacy as seen in most cases, Monero is also preferable by most people who value their privacy. I think the choice depends on every investor and this is not just a forceful opinion to hold Monero but rather it has to do choice, I still think the reason why most people don't value Monero is due to the private nature.
You have well explained it even better than i did, its not as tho monero is unpopular but not every one is interested in privacy and even if in the crypto world privacy seems to be one of the things that they ought to achieve people are not just interested in that right now, at least not those that are more interested in gain than any other thing, so yeah a lot of people mightvknow and use monero but they use it for the purpose that it was created privacy.
