Huh? You first say it doesn't pass directly in the algorithm ("blocks link juice, anchor text, and equity"), but then argue that it does ("passes value")? What part of the argument am I missing here?
If you're arguing that overall exposure to content goes up because social media sharing, then I'd be inclined to agree. Overall exposure then translates to better SEO because links are being used more often outside of non-seo-algorithmic social media (for example in blogs), hence the correlation.
