Well, for all practical purposes the same level of privacy in Bitcoin base layer as in Monero will inevitably destroy its original value proposition of provably incorruptible network.

The way I see that image, it compares privacy level between a simple privacy tool that is unsuitable as SoV, and Bitcoin the ultimate store of value. So to me it seems that it makes an assumption that whoever uses Monero as a privacy tool also needs to use it as SoV in order to practically achieve higher level of privacy. Maybe that’s just me.
