Bitcoin is a protocol and an asset, and both are close to impossible to change. 

I would be shocked if there was ever consensus on a base layer protocol change to add privacy features, especially considering how relatively mature Bitcoin is.

If that is a dealbreaker, Bitcoin is a voluntary system. No one will force you to use it.

I personally think problems with the current layered model or even Bitcoin privacy in general are greatly overstated. 

These things do not exist in a vacuum - compare them to our current financial system and you will see how incredibly superior it is.
