To be fair, scanning from a mobile device has almost zero discoverability. Few mobile OSes ship with a builtin "Scan" app in the same way that they all have a "Camera" app.

What modern societies need is a tax on feature non-discoverability; essentially providing a financial incentive for tech companies to ensure 100% of their features have meaningful uses for their users and that users can find these. At that point whatever details are economic will fall out w/o extended arguments of "what is right/best way to do X".
