Privacy is not stressed enough in crypto world! Every information is made public. No real working app can be built until the privacy problem is solved!
I really don't understand what you are trying to drive at. If you are talking about bitcoin is not anonymous, per se, its more of a pseudo-anonymity. There's a lot of privacy coins out there like Monero, Verge or Zcash.
And as far as bitcoin, privacy only because a problem is you used to scam people or bought something in the darkmarket. They can trace you back because of blockchains. Other's used tumbling services, but I think if you don't exploit bitcoin's sort of anonymity issues then I don't see it as a big hindrance to anyone in my opinion.
To simplify it privacy is more of an important issue now then scaling.
