Social media functions as a kind of gatekeeper for public interactions, not unlike credit scores, driver's licenses, and college degrees. The absence of a presence on social media is not only socially debilitating (you're cut out of the information stream for local events and public amenities) but a red-flag for college recruiters and employers. It's much like how not using a credit card regularly in your teens/20s impacts your ability to access low-interest lending in your 30s/40s. Or not having a driver's license interferes with your right to vote.

State officials have been searching for a kind of uniform, iron-clad, easily verifiable public ID for ages. Linking your online presence (a thing that you need for a myriad of daily tasks) to your ID becomes a pathway to this goal. Universal, non-transferable digital ID becomes a wicked two-edged sword as it both exhaustively tracks the "documented" individuals and neatly severs the "undocumented" from society.
