I think you would see broader adoption of this at public places if it was something you could opt into with a setting or app on your phone. Something that turns off your radios when you enter a participating public zone. Otherwise I think this would remain a niche phenomenon relegated to elite, wealthy enclaves.

Integrating this into existing apps could indeed democratize access and encourage wider use. Perhaps collaboration with popular platforms could accelerate acceptance and convenience for users across various demographics.
